selftests/bpf: Use program name for skel load/destroy functions

In preparation to migrate tests from bpf/test_sock_addr.c to
sock_addr.c, update BPF_SKEL_FUNCS so that it generates functions
based on prog_name instead of skel_name. This allows us to differentiate
between programs in the same skeleton.
