[troff]: Fix Savannah #68203.
* src/roff/troff/env.cpp (print_hyphenation_exceptions): Skip the
remainder of the input line if no hyphenation language is configured.
Fixes <https://savannah.gnu.org/bugs/?68203>. Problem introduced by me
in commit e05fb6b377, 2024-11-07 (itself a fix for a SEGV under the same
circumstance).
