[PATCH v3] libqtest: refuse QTEST_QEMU_BINARY=qemu-kvm |

Some downstreams rename the QEMU binary to "qemu-kvm". This breaks
qtest_get_arch(), which attempts to parse the target architecture from
the QTEST_QEMU_BINARY environment variable.
Print an error instead of returning the architecture "kvm". Things fail
in weird ways when the architecture string is bogus.
Arguably qtests should always be run in a build directory instead of
against an installed QEMU. In any case, printing a clear error when this
happens is helpful.
Since this is an error that is triggered by the user and not a test
failure, use exit(1) instead of abort(). Change the existing abort()
call in qtest_get_arch() to exit(1) too for the same reason and to be
consistent.
