[OE-core] [PATCH v2] oeqa/runtime/stap.py: add runtime test for systemtap

[Victor Kamensky]

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.

 v2 updates:
    * prepare in /usr/src/kernel make as in
      kernelmodule.py

    * use of uname -r for kernel release retrieval

    * adds -DSTP_NO_VERREL_CHECK to allow mismatch
      between running kernel and kernel-devsrc
