GCC 13.2.0 reported the warning of the print format specifier:

conf.c: In function ‘sysfs_get’:
conf.c:181:72: warning: format ‘%s’ expects argument of type ‘char *’, \
			but argument 3 has type ‘int’ [-Wformat=]
  181 |                 ksft_exit_fail_msg("sysfs: unable to read value '%s': %s\n",
      |                                                                       ~^
      |                                                                        |
      |                                                                        char *
      |                                                                       %d

The fix passes strerror(errno) as it was intended, like in the sibling error
exit message.
