[arm-allstar] connpgm issue

[Kevin Davis]

I've been running a python3 script as my connpgm and discpgm for playing
some tones and sending myself an SMS:

connpgm=python3 /usr/local/sbin/connpgm.py C
discpgm=python3 /usr/local/sbin/connpgm.py D

Since the update, it began failing.
[Jan  5 14:40:55] ERROR[8307]: app_rpt.c:16511 doprogram: exec of python3
failed.

Adding a shebang(#!/usr/bin/python3), making it executable, and removing
the 'python3' from the connpgm setting fixed my issue.

Just thought I'd mention it since it seems tied to updating my node and
might be plaguing others.
