rG7b9c912c41f4: find: Add GNU find's -printf

Summary

Implements most of gnu find's -printf predicate. However, the '#', '-',
'.' and size format modifiers are unimplemented, as are %P, %H, %F, %y,
and %Y formats. Follows what I think it should do based on the info
page, I've not looked at the gnu find code.

13	probably added by accident :D
14	nitpicking here, but maybe consider open_memstream instead of sbuf? it will avoid adding an extra link to sbuf library for a very limited usage. feel free to totally ignore this nitpicking comment

14	Sure. I resisted for a while, but the conversion was quicker than arguing :)

usr.bin/find/function.c
1410	We only need to force stat if certain formats are used. If it's just `%p`/`%f`/`%h` and literals, no stat calls are necessary.
usr.bin/find/printf.c
271	This will run off the end of the string if `*fmt == '\0'`.
283	typo

Usually LGTM, besides the part of the XXX (see comment).

usr.bin/find/find.1
1077	This should be written out or removed. Otherwise LGTM.

1410	Oh my. Seems like I overlooked this. Fixed in a followup commit. Thanks for catching it.
usr.bin/find/printf.c
106	I'm not sure how to parse this. Can you say again in another way?
