android/binder.h: add linux/android/binder(fs).h to UAPI compile-test coverage

linux/android/binder.h and linux/android/binderfs.h are currently
excluded from the UAPI compile-test because of the errors like follows:

    HDRTEST usr/include/linux/android/binder.h
  In file included from <command-line>:
  ./usr/include/linux/android/binder.h:291:9: error: unknown type name ‘pid_t’
    291 |         pid_t           sender_pid;
        |         ^~~~~
  ./usr/include/linux/android/binder.h:292:9: error: unknown type name ‘uid_t’
    292 |         uid_t           sender_euid;
        |         ^~~~~

The errors can be fixed by replacing {pid,uid}_t with __kernel_{pid,uid}_t.

Then, remove the no-header-test entries from user/include/Makefile.
