  iotests.py: Enable faulthandler

With this, you can send SIGABRT to a hanging test case and you'll get a
Python stack trace so you know where it was hanging.

  python/qemu: Kill QEMU process if 'quit' doesn't work

With a QEMU bug, it can happen that the QEMU process doesn't react to a
'quit' QMP command. If we got an exception during previous QMP
communication (e.g. iotests Timeout expiring), we could also be in an
inconsistent state where after sending 'quit' we immediately read an old
response and close the socket even though the 'quit' command wasn't
processed yet. Both cases would lead to a hanging test.

Fix this by waiting for the QEMU process to exit after sending 'quit'
with a timeout, and if it doesn't happen within three seconds, send
SIGKILL.

  iotests: Increase pause_wait() timeout

Waiting for only 1 second proved to be too short on a loaded system,
resulting in false positives when testing pull requests. Increase the
timeout a bit to make this less likely.
