firefox: update to 88.0.1
https://github.com/void-linux/void-packages/pull/30718

Description:
- firefox: update to 88.0.1
- firefox-i18n: update to 88.0.1
- firefox: add musl patch

I took the patch from Alpine, hoping that it would allow firefox to run on musl 1.2.2.
Possibly more patches are needed, but at least this one shouldn't do any damage.
I haven't built/tested it on musl yet.
