This is a magic global variable that was intended as an
override to the usual git-config lookup process. Once upon a
time, you could specify GIT_CONFIG to any git program, and
it would look only at that file. This turned out to be
confusing and cause a lot of bugs for little gain. As a
result, dc87183 (Only use GIT_CONFIG in "git config", not
other programs, 2008-06-30) took this away for all callers
except git-config.
Since git-config no longer uses it either, the variable can
just go away. As the diff shows, nobody was setting to
anything except NULL, so we can just replace any sites where
it was read with NULL.

This could be squashed into the last patch (really, all of the last few
patches could be squashed). But I was able to "git grep
config_exclusive_filename" at this state and see that yes, indeed, the
variable is now totally useless.
