perf bpf: Remove bpf/ subdir from bpf.h headers used to build bpf events
The bpf.h file needed gets installed in /usr/lib/include/perf/bpf/bpf.h,
and /usr/lib/include/perf/ is added to the include path passed to clang
to build the eBPF bytecode, so just remove "bpf/", its directly in the
path passed already. This was working by accident, fix it.
I.e. now this is back working:
# cat /home/acme/git/perf/tools/perf/examples/bpf/hello.c
#include <stdio.h>
int syscall_enter(openat)(void *args)
{
puts("Hello, world\n");
return 0;
}
license(GPL);
# perf trace -e /home/acme/git/perf/tools/perf/examples/bpf/hello.c
