Really kill subprocesses of a test case before waiting for its completion

Before waiting for any leftover output of the test case after it terminates,
we must ensure that all of its subprocess are really, really dead.  Otherwise,
these subprocesses may be sharing the stdout of the test case, in which case
our wait will block (potentially indefinitely).

This finally (well, hopefully) fixes some random lockups exposed by the
NetBSD test suite.  Reported by Antti Kantee after
tests/fs/vfs/t_full:p2k_ffs_fillfs was exposing this problem in a pretty
reproducible manner.
