Since the split out of git-perltools, some git tools (such as "git am",
"git send-email" and "git-submodule") have no longer been part of the
buildtools. We need these, so add them back in.
However, adding git-perltools to buildtools triggers perl itself being
brought into buildtools as well, and we don't want that; but we also
don't want to have to hack the git recipe or indeed anything else that
starts depending on perl. Thus, add a dummy package which gets installed
in its place, in a separate package architecture that is only enabled
for buildtools to ensure it doesn't start appearing in place of
nativesdk-perl anywhere else.
Fixes [YOCTO #7033].
