On latest RT kernels we are getting following errors while compiling OVS:

This happened because RT kernel has used raw keyword inside skbuff.h, which was
used to identify some older kernels stuff in OVS.
Lets make the search pattern a bit stronger by searching "*raw;" instead of
"raw".

V1->V2:
- Instead of removing OVS_GREP_IFELSE() for searching raw, make grep pattern
stronger.
