Eric Blake 71a268a5fd tests/libqtest: Improve kill_qemu() 
In kill_qemu() we have an assert that checks that the QEMU process
didn't dump core:
            assert(!WCOREDUMP(wstatus));

Unfortunately the WCOREDUMP macro here means the resulting message
is not very easy to comprehend on at least some systems:

ahci-test: tests/libqtest.c:113: kill_qemu: Assertion `!(((__extension__ (((union { __typeof(wstatus) __in; int __i; }) { .__in = (wstatus) }).__i))) & 0x80)' failed.

and it doesn't identify what signal the process took. What's more,
WCOREDUMP is not reliable - in some cases, setrlimit() coupled with
kernel dump settings can result in the flag not being set.  It's
better to log ALL death by signal, instead of caring whether a core
dump was attempted (although once we know a signal happened, also
mentioning if a core dump is present can be helpful).

Furthermore, we are NOT detecting EINTR (while EINTR shouldn't be
happening if we didn't install signal handlers, it's still better
to always be robust).

Finally, even non-signal death with a non-zero status is suspicious,
since qemu's SIGINT handler is supposed to result in exit(0).

Instead of using a raw assert, print the information in an
easier to understand way:

/i386/ahci/sanity: tests/libqtest.c:129: kill_qemu() detected QEMU death from signal 11 (Segmentation fault) (core dumped)

(Of course, the really useful information would be why the QEMU
process dumped core in the first place, but we don't have that
by the time the test program has picked up the exit status.)
