remove xbmk_parent, handle forking in lib.shHEADmaster

I was using a complicated method of knowing whether
the current instance was parent or a child, to know
whether the lock file and TMPDIR needed to be purged.

It was quite error-prone too. Instead, I'm now handling
it directly from within the if statement that previously
initialised xbmk_parent=y, forking ./mk from there.

The forked instance would not trigger that if clause
again, since then TMPDIR is created, thus avoiding
recursion.

This is an improvement because it doesn't rely on how
the parent handles exit statuses, and it ensures that
the lock/tmp files are never accidentally deleted.

Even if a given program/script that lbmk runs would
export TMPDIR, it doesn't matter because lbmk doesn't,
so it would be unaffected.
