selftests/bpf: Add unit tests for bpf_arena_alloc/free_pages
Add unit tests for bpf_arena_alloc/free_pages() functionality
and bpf_arena_common.h with a set of common helpers and macros that
is used in this test and the following patches.
Also modify test_loader that didn't support running bpf_prog_type_syscall
programs.
