net/gsocket: add missing run-time dependency on GNU Bash

This port installs a number of shell scripts riddled with bashisms,
most notably, double bracket expressions, so fixing them to become
POSIX shell-compliant does not look feasible or, rather, practical.

While here, shorten the COMMENT without sacrificing its meaning so
``pkg search gsocket'' or ``pkg info | grep gsocket'' would fit in
standard 80-character terminal and fix one minor whitespace nit.
