After moving to pathlib, searching for modelsim.ini is done in a different directory

[suoto]

When moving to using pathlib (commit 1af5128) I believe there's a mistake here

vunit/vunit/sim_if/modelsim.py

Lines 72 to 73 in bcdabe4

	def has_modelsim_ini(path):
	return os.path.isfile(str(Path(path) / "modelsim.ini"))

The previous code searched for modelsim.ini one level above the executable:

def has_modelsim_ini(path): 
     return os.path.isfile(join(path, "..", "modelsim.ini")) 

A suggested fix would be

def has_modelsim_ini(path):
    return os.path.isfile(str(Path(path).parent / "modelsim.ini"))

If the vsim executable can be located, one could use vmap to work out where modelsim.ini is (it also respects the MODELSIM environment variable)

$ vmap
Reading /home/souto/modelsim/modeltech/linux_x86_64/../modelsim.ini
"std" maps to directory /home/souto/modelsim/modeltech/linux_x86_64/../std.
"ieee" maps to directory /home/souto/modelsim/modeltech/linux_x86_64/../ieee.
...

I applied the suggested fix. Thanks for reporting!

Implemented in #975. Thanks for the idea!
