[PATCH] git-apply tests need to be portable

[Don Zickus <dzickus@redhat.com>]

When I created the tests for my git-apply patch, I accidently used the '-i'
flag for sed.  Not all versions of sed handle this flag, so I converted
those instances to output to a temp file and move that temp file back to the
original file.

Thanks to Jim Meyering for noticing this!

Junio, I am not sure if you want me to resend the whole patch again or is a
small update like this preferred.  I am indifferent either way.

Cheers,
Don
