MinGW: disable CRT command line globbing
MingwRT listens to _CRT_glob to decide if __getmainargs should
perform globbing, with the default being that it should.
Unfortunately, __getmainargs globbing is sub-par; for instance
patterns like "*.c" will only match c-sources in the current
directory.
Disable __getmainargs' command line wildcard expansion, so these
patterns will be left untouched, and handled by Git's superior
built-in globbing instead.
MSVC defaults to no globbing, so we don't need to do anything
in that case.
This fixes t5505 and t7810.
