tests: merge 'test-push-hook-lock.t' into 'test-push.t'

That test file is very small and is merge with the new 'test-push.t'. No logic
is changed.

We don't register this as a copy because is actually a "ypoc" merging two file
together without replacing the destination and Mercurial cannot express that.
