qapi: Add exit-failure PanicAction

Currently QEMU exits with code 0 on both panic an shutdown. For tests
it is useful to return 1 on panic, so that it counts as a test
failure.

Introduce a new exit-failure PanicAction that makes main() return
EXIT_FAILURE. Tests can use -action panic=exit-failure option to
activate this behavior.
