Remove incompatible Digium codec_opus — crashes Asterisk on Ubuntu 24.04

The Digium precompiled codec_opus.so is ABI-incompatible with Ubuntu
24.04's Asterisk package build, causing "Module initialization failed.
ASTERISK EXITING!" on startup. The format_ogg_opus.so also conflicts
with the one already in asterisk-modules.

Opus pass-through (phone-to-phone when both support Opus) still works
via res_format_attr_opus.so from asterisk-modules. Only Opus<->ulaw
transcoding is unavailable, which is rarely needed since modern SIP
phones support the same codecs natively.

Changes:
- Remove Digium codec download from Dockerfile
- Add noload for codec_opus.so and format_ogg_opus.so in modules.conf
- Add startup cleanup to remove stale Digium .so files from Docker volume
