fix a annex.pidlock issue

That made eg git-annex get of an unlocked file hang until the
annex.pidlocktimeout and then fail.

This fix should be fully thread safe no matter what else git-annex is
doing.

Only using runsGitAnnexChildProcess in the one place it's known to be a
problem. Could audit for all places where git-annex runs itself as a child
and add it to all of them, later.
