tests/qtest/libqtest: Fix detection of architecture for binaries without path 

The qtests can be run directly by specifying the QEMU binary with the
QTEST_QEMU_BINARY environment variable, for example:

 $ QTEST_QEMU_BINARY=x86_64-softmmu/qemu-system-x86_64 tests/qtest/test-hmp

However, if you specify a binary without a path, for example with
QTEST_QEMU_BINARY=qemu-system-x86_64 if the QEMU binary is in your
$PATH, then the test currently simply crashes.

Let's try a little bit smarter here by looking for the final '-'
instead of the slash.
