bitbake: git-make-shallow: use stdin mode

Browse Source 
when there are many refs to delete, using xargs to exec git can take a very long
time. make this faster by only running git update-ref with stdin mode.

for a repo with over 34000 git tags this makes git-make-shallow finish
in 2 seconds instead of 3 minutes for me.

(Bitbake rev: 2b815e42ec074a7f8667bbfaccaa69fc4a0ba788)
