[PATCH v2] checkpatch: add new exception to repeated word check

[Dwaipayan Ray]

Recently, commit 4f6ad8aa1eac ("checkpatch: move repeated word test")
moved the repeated word test to check for more file types. But after
this, if checkpatch.pl is run on MAINTAINERS, it generates several
new warnings of the type:

WARNING: Possible repeated word: 'git'

For example:
WARNING: Possible repeated word: 'git'
+T:	git git://git.kernel.org/pub/scm/linux/kernel/git/rw/uml.git

So, the pattern "git git://..." is a false positive in this case.

Add 'git' to the exception list for repeated word check. This effectively
fixes all the newly generated false positives.
