Bug 1732580 - Allow read access to files under $SNAP/ in the webcontent sandbox.
### ESR Uplift Approval Request
* **If this is not a sec:{high,crit} bug, please state case for ESR
consideration**: Snap packaging has changed significantly between ESR78 and
ESR91. In ESR78 WebGL works in Wayland sessions, whereas it doesn't in ESR91,
making it a very visible functional regression.
* **User impact if declined**: WebGL doesn't work for users of the firefox snap
in Wayland sessions.
* **Fix Landed on Version**: 94.0b5
* **Risk to taking this patch**: Low
* **Why is the change risky/not risky? (and alternatives if risky)**: Not risky
because only the snap package is affected (the sandbox allows one additional
folder for readonly access if the $SNAP environment variable is set).
* **String or UUID changes made by this patch**:

After that, I logged under x11 (for test) but wasn't able to launch firefox:
Error: cannot open display: :0
I had to reboot and the problem occurs only with wayland.
