This commit changes the _kern suffix to .bpf with the BPF test programs.
With this modification, test programs will inherit the benefit of the
new CLANG-BPF compile target.

We have switched to memcg-based memory accouting and thus the rlimit is
not needed any more. LIBBPF_STRICT_AUTO_RLIMIT_MEMLOCK was introduced in
libbpf for backward compatibility, so we can use it instead now.
This patch also removes the useless header sys/resource.h from many files
in samples/bpf.

Since bpf is not using rlimit memlock for the memory accounting
and control, do not change the limit in sample applications.

From commit 646f02ffdd49 ("libbpf: Add BTF-defined map-in-map
support"), a way to define internal map in BTF-defined map has been
added.
Instead of using previous 'inner_map_idx' definition, the structure to
be used for the inner map can be directly defined using array directive.
__array(values, struct inner_map)
This commit refactors map in map test program with libbpf by explicitly
defining inner map with BTF-defined format.

There are two files in the tree called libbpf.h which is becoming
problematic. Most samples don't actually need the local libbpf.h
they simply include it to get to bpf/bpf.h. Include bpf/bpf.h
directly instead.
