pt_BR: Fix wrong translation of Disk Image Mounter

[fvGYVlADdOvIsb84]

The pt_BR translation for "Disk Image Mounter" was incorrectly translated
as "Analisador de Uso do Disco MATE", which corresponds to Baobab (Disk Usage Analyzer).

This patch corrects it to:
"Montador de Imagens de Disco do MATE".

@raveit65 do we still use Transifex for translations? How does tx sync work? I suspect we don't edit po files by hand, right?

@vkareh
Yes , we do not edit po files by hand.
At https://app.transifex.com/mate/ organization you will find 2 projects.

• MATE Desktop Environment
• MATE Desktop Website

Every github repository use 2 resources (master and released branch), you will find them under MATE Desktop Environment.
https://app.transifex.com/mate/MATE/content/ (MATE=MATE Desktop Environment)
Note, as i can see transifex use actual 1.26 and master. Means for github repositories where 1.28 is branched you need to update transifex resources. (adding 1.28 and deleting 1.26 resource)
This can be done by so called organization administrator . Currently active MATE members with that role are @mbkma and @lukefromdc . I added you as admin now ;-)
How a translation update works:

1. compile the repository and run makepot script. In case of mate-utils this will create/update 5 *.pot files, see script.
2. commit and push the change
3. Transifex monitor ie. https://github.com/mate-desktop/mate-utils/blob/master/mate-disk-usage-analyzer.pot for updates 2 times a day. This example url needs to be added in raw format when you create an new resources for 1.28.
4. Now Translators can translate the update. This needs some time....
5. Updated translations can be pull from transifex with the transifex-client.
   sudo dnf install transifex-client
6. You need a ~/.transifexrc for token auth, see https://developers.transifex.com/docs/cli
7. Now Run ie. tx pull -a -f
   I used the --minimum-perc=1 option, means miminum translation percentage = 1, so it skips empty translation pos and brings ones with 1 or more msgstr.
   I recall i added this option to ~/.transifexrc.
   Sadly i do not have this file anymore at my notebook.
   Important: check repository that translation update doesn't break building! Translators do often create string format mistakes, which needs to be fixed by hand in their language at transifex page. ....a very thankless job.
8. Commit new translations and push it to github

Let me know if you have more questions.

For adding a new resource.

For adding the url as automatic update to the new resource click on the three point.

After adding check that it look like this.

Double -- in url is important.

Well, in case of this PR @fvGYVlADdOvIsb84 needs to become a member of pt_BR language group and should fix the translation there.
