Bug Description

The chromium-browser deb package has a patch that allows the browser to look for the content decryption module in /opt/google/chrome/ and use it if present (assumes google-chrome is also installed).

This won't work with the snap, because the snap's runtime environment won't use /opt from the host.

What could work is to patch chromium to look for libwidevinecdm.so somewhere within the snap's area ($SNAP_USER_COMMON or $SNAP_USER_DATA), and have instructions for the user to copy the file to this area.
