tests: Deduplicate some WITH_* checks

When constructing mock_libs array it is firstly initialized to a
static set of mocks followed by couple of WITH_* checks to append
driver specific mocks. These checks are then repeated when
filling some other variables (e.g. supplementary helpers,
libraries, tests, etc.). Dissolve the former in the latter since
we are already doing that, partially, for qemu (qemucapsprobemock
and qemuhotplugmock)
