Use /bin/sh interpreter instead of /bin/bash for contrib/git-subtree:
it's required for systems which don't use bash by default (for example,
FreeBSD), while there seem to be no bashisms in the script (confirmed
by looking through the source and tesing subtree functionality with
FreeBSD's /bin/sh) to require specifically bash and not the generic
posix shell.

Has anybody audited to make sure that the script itself is free of
bash-isms?
I somehow had an impression that in the past it was littered with
bash-isms like function local variables and array variables and
assumed that the #!/bin/bash was necessary. I did a quick
eyeballing and did not see anything glaringly bash-only, but I may
have missed something (the coding style is so different from the
core part of Git Porcelains and distracting for me to efficiently
do a good job of scanning).

I ran the test suite with dash and everything passed.
checkbashisms doesn't find any problems either.
