Add FETCHCMD parameter for git

The Git fetcher currently hardwires the git command to "git". Allow the
path and any additional wrappers to the Git command to be provided via
FETCHCMD functionality, as with some of the other fetchers.

If FETCHCMD_git is not define in bitbake.conf, the fetcher defaults to "git".
