selftests/bpf: sync kernel headers and introduce arch support in Makefile

Browse Source 
Synchronize the uapi kernel header files which solves the broken
uapi export of pt_regs.  Because of arch-specific uapi headers,
extended the include path in the Makefile.

With this change, the test_verifier program compiles and runs successfully
on s390.
