perf beauty: Add generator for fsmount's 'attr_flags' arg values

  $ tools/perf/trace/beauty/fsmount.sh
  static const char *fsmount_attr_flags[] = {
          [ilog2(0x00000001) + 1] = "RDONLY",
          [ilog2(0x00000002) + 1] = "NOSUID",
          [ilog2(0x00000004) + 1] = "NODEV",
          [ilog2(0x00000008) + 1] = "NOEXEC",
          [ilog2(0x00000010) + 1] = "NOATIME",
          [ilog2(0x00000020) + 1] = "STRICTATIME",
          [ilog2(0x00000080) + 1] = "NODIRATIME",
  }

MOUNT_ATTR__ATIME and MOUNT_ATTR_RELATIME will be special cased in the
fsmount__scnprintf_flags() beautifier.
