[PULL 11/20] tests/qtest/readconfig-test: Check for the availability of USB controllers

[Thomas Huth <thuth@redhat.com>]

The USB controllers might not be available in the QEMU binary
(e.g. when using the "--without-default-devices" configure switch),
so we have to check whether the devices can be used before running
the related test.
