Clean Zygote traces for multiple times

[JingMatrix]

For users with many modules installed, a single pass of Zygote trace cleaning could be insufficient to discover all mounting traces due to timing issue.

We add field zygote_unmounted_times to unmount up to 5 rounds in nativeForkAndSpecialize_pre.
