[PATCH v4 2/5] perf build: Sync bpf_skel.mak get_sys_includes with selftests/bpf

[Ian Rogers <irogers@google.com>]

Forward __loongarch_grlen as -D__BITS_PER_LONG and the MIPS ABI, size,
and endianness macros in bpf_skel.mak's get_sys_includes, matching
tools/testing/selftests/bpf/Makefile so system headers receive the
expected architecture macros when compiling BPF skeletons.
