Fix directory navigation in Dolphin::Terminal.

When navigating in Dolphin it attempts to keep any open Terminal (F4)
in sync by changing the directory in the shell.  It does this by
sending a "^C; cd $DIRECTORY" however shells under FreeBSD treat "^C"
as a literal string and not SIGINT.  Fix this by sending SIGINT to the
shell instead of "^C".

It appears Linux does not exhibit this behaviour.

Patch originally written by David Naylor, from the KDE-FreeBSD team.
