Fix receive-pack

If we quote as --receive-pack="git receive-pack --reviewer=foo@example.com",
git will try to run "git receive-pack --reviewer=foo@example.com" command
and failed like this

Gerrit Code Review: git receive-pack --reviewer=foo@example.com: not found
fatal: The remote end hung up unexpectedly
Command "git push --receive-pack="git receive-pack --reviewer=foo@example.com" origin HEAD:refs/for/master" failed.
