bpf, selftests: Fix cast to smaller integer type 'int' warning in raw_tp
Fix warning in bpf selftests,
progs/test_raw_tp_test_run.c:18:10: warning: cast to smaller integer type 'int' from 'struct task_struct *' [-Wpointer-to-int-cast]
Change int type cast to long to fix. Discovered with gcc-9 and llvm-11+
where llvm was recent main branch.
Fixes: 09d8ad16885ee ("selftests/bpf: Add raw_tp_test_run")
