EX-9585 lipe: add lipe_find3 projid option

Add an option to print the project ID for a file with the
"-printf" argument, both as long option %{projid} as well
as short option and "%LP" that is compatible with "lfs find".

Sort all of the existing and new options alphabetically so that
it is easier to see which ones are implemented in the future.

Update the lipe-find3.1 man page and add a test case.
