Bug 1725828 - Preload dependencies for the Widevine CDM when sandboxing it on
Linux.
### ESR Uplift Approval Request
* **If this is not a sec:{high,crit} bug, please state case for ESR
consideration**: Widevine EME and H.264 WebRTC may be broken depending on how
Firefox is built.
* **User impact if declined**: This doesn't affect Mozilla's builds and
probably won't affect them for some time, but downstream builds (already on
some Linux distributions, and probably more and more in the future) won't be
able to use the Widevine plugin for EME or OpenH264 for WebRTC.
* **Fix Landed on Version**: 94
* **Risk to taking this patch**: Low
* **Why is the change risky/not risky? (and alternatives if risky)**: We just
preload some libraries which are normally already loaded; the patch is small
and should have no effect on builds that weren't affected by this bug (like
Mozilla's).
One alternative is to require downstream distributions to apply the patch
themselves if they intend to build ESR91 with a recent glibc, but as far as I
know there's no good way to communicate that to everyone who needs to hear it,
and failures are likely to result in more bug reports for us.
* **String or UUID changes made by this patch**: none
