fix: add missing set_debug_mode function to kugetsu-session.sh

The queue daemon crashes with 'set_debug_mode: command not found' because
cmd_continue() calls set_debug_mode(), but that function was only defined
in the main kugetsu script, not in kugetsu-session.sh which the daemon
sources directly.

Fixes #207
