The task passed the script `${shairport_sync_version}` - shell syntax in a Jinja field,
and the wrong variable name - which the Pi's shell expanded to nothing, so the script
fell back to its own default. Its `git reset` then ran outside the fresh clone, failed,
and was ignored without `set -e`: every build was simply upstream master. The script
now takes `pi_shairport_sync_version`, requires the argument, clones that tag directly
and stops on the first error. Bumped to 4.3.7.
