Adds domain/username in error message, if owner sid of repository and
user sid are not equal on windows systems.

Old Prompted error message:
'''
fatal: detected dubious ownership in repository at 'C:/Users/test/source/repos/git'
'C:/Users/test/source/repos/git' is owned by:
	'S-1-5-21-571067702-4104414259-3379520149-500'
but the current user is:
	'S-1-5-21-571067702-4104414259-3379520149-1001'
To add an exception for this directory, call:

	git config --global --add safe.directory C:/Users/test/source/repos/git
'''

New prompted error massage:
'''

Looking at past commits that worked on the area this patch touches,
namely, 7c83470e (mingw: be more informative when ownership check
fails on FAT32, 2022-08-08) and e883e04b (mingw: provide details
about unsafe directories' ownership, 2022-08-08), I would retitle
the commit perhaps like so:

    Subject: [PATCH v5] mingw: give more details about unsafe directory's ownership

if I were doing this patch.

I probably would drop two "prompted" from the above, too, if I were
doing this patch.

Thanks for working on making this error message more readable.  I'll
queue it when I see an Ack from Dscho.
