tests/libqtest: Use a proper error message if QTEST_QEMU_BINARY is missing

The user can currently still cause an abort() if running certain tests
(like the prom-env-test) without setting the QTEST_QEMU_BINARY first.
A similar problem has been fixed with commit 7c933ad61b
already, but forgot to also take care of the qtest_get_arch() function,
so let's introduce a proper wrapper around getenv("QTEST_QEMU_BINARY")
that can be used in both locations now.
