Well, it's a one-to-many due to how the personality types are defined,
so doing a bitfield-to-ASCII-names conversion wouldn't really work out:

PER_SCOSVR3 = 0x0003 | STICKY_TIMEOUTS |
WHOLE_SECONDS | SHORT_INODE,
PER_OSR5 = 0x0003 | STICKY_TIMEOUTS | WHOLE_SECONDS,
...
PER_BSD = 0x0006,
PER_SUNOS = 0x0006 | STICKY_TIMEOUTS,

But I can certainly just make it a stand-alone file with just the
bitfield. Or, I can still do the conversion and ignore PER_OSR5 and
PER_SUNOS.
