selftests/x86/pkeys: Remove unused functions



This also gets rid of two build warnings:

  protection_keys.c: In function ‘dumpit’:
  protection_keys.c:419:3: warning: ignoring return value of ‘write’, declared with attribute warn_unused_result [-Wunused-result]
     write(1, buf, nr_read);
     ^~~~~~~~~~~~~~~~~~~~~~
