Revert "selftest: Added MACHINE = "qemux86" to tests that use runqemu"
This is not the correct way to handle this - it significantly increases
the time taken to run oe-selftest anywhere MACHINE is set to some other
value (for example "qemux86-64"), because all of the artifacts for
qemux86 need to then be built as well when running the test. If we need
to skip these tests on non-QEMU machines, the devtool test already
demonstrates how to do that.
