Enable building multiple test programs and related kernel modules, with
initial support for the bpf_testmod.ko module required since kernel 6.4.
Explicitly disable LTO and clean up makefile variables and formatting.
Fix a musl-related build failure by adding a kernel 6.6 patch:
360-selftests-bpf-portability-of-unprivileged-tests.patch

Make use of new toolchain define. TOOLCHAIN_DIR should be used only for
toolchain related packages and for everything else TOOLCHAIN_ROOT_DIR
and other define should be used instead.
Switch to new entry where possible.

Build and package kernel self-tests used for BPF testing, program and JIT
development. This package, together with the existing 'kmod-bpf-test', was
extensively used for past upstream Linux JIT submissions [1].
Currently this includes only 'test_verifier'; building 'test_progs' will
fail due to known endian limitations with bpftool skeletons.
