This set enables BPF_PROG_TEST_RUN for raw_tracepoint type programs. This
set also enables running the raw_tp program on a specific CPU. This feature
can be used by user space to trigger programs that access percpu resources,
e.g. perf_event, percpu variables.

Changes v2 => v3:
1. Fix memory leak in the selftest. (Andrii)
2. Use __u64 instead of unsigned long long. (Andrii)

Changes v1 => v2:
1. More checks for retval in the selftest. (John)
2. Remove unnecessary goto in bpf_prog_test_run_raw_tp. (John)

I somehow missed Andrii's other comments and sent v3 too fast. 

Please ignore this version.
