Requires https://pagure.io/iceweasel/pull-request/11

Update according to 119.0 changes from upstreams. Mozilla has added
Remote Settings client written in Rust, but from what I understood,
currently it's used only to fetch the data for suggestions called
Firefox Suggest, which include sponsored suggestions, of course. It
doesn't appear to support local dumps currently, so if more features
start using Rust client, it'll probably need further patching.

Built for x86_64 with _USE_ALT_LINKER=0 (Arch Linux way) with zram
trickery mentioned in https://pagure.io/abslibre/pull-request/89

Didn't try to build on i686 and armv7h, also didn't check if there were any
updates from their upstreams, sorry for that.
