qtest: Fix crash if SIGABRT during qtest_init()
If an assertion fails during qtest_init() the SIGABRT handler is
invoked. This is the correct behavior since we need to kill the QEMU
process to avoid leaking it when the test dies.
The global_qtest pointer used by the SIGABRT handler is currently only
assigned after qtest_init() returns. This results in a segfault if an
assertion failure occurs during qtest_init().
Move global_qtest assignment inside qtest_init(). Not pretty but let's
face it - the signal handler depends on global state.
