tests/qtest/vhost-user-blk-test: Check whether qemu-storage-daemon is available

Browse Source 
The vhost-user-blk-test currently hangs if QTEST_QEMU_STORAGE_DAEMON_BINARY
points to a non-existing binary. Let's improve this situation by checking
for the availability of the binary first, so we can fail gracefully if
it is not accessible.
