selftests/bpf: Test freplace from user namespace

Add selftests to verify that it is possible to load freplace program
from user namespace if BPF token is initialized by bpf_object__prepare
before calling bpf_program__set_attach_target.
Negative test is added as well.

Modified type of the priv_prog to xdp, as kprobe did not work on aarch64
and s390x.
