selftests/bpf: Make selftest compilation work on clang 11
We can't compile test_core_reloc_module.c selftest with clang 11, compile fails with: CLNG-LLC [test_maps] test_core_reloc_module.o progs/test_core_reloc_module.c:57:21: error: use of unknown builtin \ '__builtin_preserve_type_info' [-Wimplicit-function-declaration] out->read_ctx_sz = bpf_core_type_size(struct bpf_testmod_test_read_ctx); Skipping these tests if __builtin_preserve_type_info() is not supported by compiler.
