Use rev-parse to find gitdir when generating commit-msg hook hint

This updates the Change-Id validator hint to advise the user to use
"git rev-parse --git-dir" to find the proper gitdir, in case the
user is using submodules.  Also, the gitdir is stored into a temp
variable, because msysgit has an unusual behavior related to the
path returned by rev-parse otherwise.
