library: add abbreviated TTY_NUMBER to that <pids> API

Browse Source 
While not documented in the man page, ps allows 'tty4'
as a valid output specifier complimenting 'tty8' & its
derivatives. So, in order to eliminate a dev_to_name()
call in the ps program the library will now offer this
abbreviated tty version (consisting of a number only).
