test-lib-functions: detect test_when_finished in subshell
test_when_finished does nothing in a subshell because the change to
test_cleanup does not affect the parent.
There is no POSIX way to detect that we are in a subshell ($$ and $PPID
are specified to remain unchanged), but we can detect it on Bash and
fall back to ignoring the bug on other shells.
