Fix CAM_NAME bug, set -x noise, wrong Python package in README

daily_sunrise_video.sh: derive CAM_NAME from $1 (defaulting to SUNRISE_CAM)
instead of an undefined variable; this was causing empty image/output paths.

install.sh: pass $SUNRISE_CAM as argument to daily_sunrise_video.sh so it
matches the pattern used by every other per-camera script.

sunrise2mm.py: use SUNRISE_CAM config key (not the undefined CAM_NAME) to
locate the output directory; fixes silent path mismatch on non-default names.

4-seasons.sh: remove stray `set -x` that was flooding systemd logs with
shell trace output.

README.md: correct Python dependencies from `ephem` to `suntime pytz` to
match what sunrise.py actually imports.
