selftests/bpf: fix broken build due to types.h
Commit 0a5539f66133 ("bpf: Provide a linux/types.h override for bpf selftests.") caused a build failure for tools/testing/selftest/bpf because of some missing types: $ make -C tools/testing/selftests/bpf/ ... In file included from /home/yhs/work/net-next/tools/testing/selftests/bpf/test_pkt_access.c:8: ../../../include/uapi/linux/bpf.h:170:3: error: unknown type name '__aligned_u64' __aligned_u64 key; ... /usr/include/linux/swab.h:160:8: error: unknown type name '__always_inline' static __always_inline __u16 __swab16p(const __u16 *p) ... The type __aligned_u64 is defined in linux:include/uapi/linux/types.h. The fix is to copy missing type definition into tools/testing/selftests/bpf/include/uapi/linux/types.h. Adding additional include "string.h" resolves __always_inline issue. Fixes: 0a5539f66133 ("bpf: Provide a linux/types.h override for bpf selftests.")
