Subject: [PATCH] selftests: futex: set DEFAULT_INSTALL_HDR_PATH

If only futex selftest is compiled, uapi header files are copied to the
selftests/futex/functional directory. This copy isn't needed. Set the
DEFAULT_INSTALL_HDR_PATH variable to 1 to use the default header install
path only. This removes extra copy of header file.

I've tried the following variations. The build is fine.

cd tools/testing/selftests/futex/functional
make

cd tools/testing/selftests/futex/
make

make -C tools/testing/selftests/

This must have been fixed in previous changes made to the build system.

This will be a good cleanup. However, please make there is no dependencies
in the futex test sub-dirs on being able to find the headers under futex

I vaguely remember leaving this in place for reason.

Thanks for checking. I will apply this in for Linux 5.18-rc1
