tools/bpf: Move linux/types.h for selftests and bpftool
Commit fe4eb069edb7 ("bpftool: Use linux/types.h from source tree for profiler build") added a build dependency on tools/testing/selftests/bpf to tools/bpf/bpftool. This is suboptimal with respect to a possible stand-alone build of bpftool. Fix this by moving tools/testing/selftests/bpf/include/uapi/linux/types.h to tools/include/uapi/linux/types.h. This requires an adjustment in the include search path order for the tests in tools/testing/selftests/bpf so that tools/include/linux/types.h is selected when building host binaries and tools/include/uapi/linux/types.h is selected when building bpf binaries. Verified by compiling bpftool and the bpf selftests on x86_64 with this change.
