Convert a bunch of selftests to using newly added high-level BPF map
APIs.
This change exposed that map_kptr selftests allocated too big buffer,
which is fixed in this patch as well.

Embed contents of BPF object file used for BPF skeleton generation inside
skeleton itself. This allows to keep BPF object file and its skeleton in sync
at all times, and simpifies skeleton instantiation.
Also switch existing selftests to not require BPF_EMBED_OBJ anymore.
