Subject: [PATCH v1 bpf-next] selftests/bpf : Clean up feature/ when make clean

I got an error when compiling selftests/bpf:

libbpf.c:411:10: error: implicit declaration of function 'reallocarray';
did you mean 'realloc'? [-Werror=implicit-function-declaration]
  progs = reallocarray(progs, nr_progs + 1, sizeof(progs[0]));

It was caused by feature-reallocarray=1 in FEATURE-DUMP.libbpf and it
was fixed by manually removing feature/ folder. This diff adds feature/
to EXTRA_CLEAN to avoid this problem.
