oeqa/runtime/stap.py: add runtime test for systemtap

Add runtime test for stap to test basic SystemTap
operations: can compile very basic module and run on
target device.

Note we disable (-DSTP_NO_VERREL_CHECK) SystemTap
additional kernel release check since during OE testing
mismatching kernel-devsrc and kernels are used.
