Include musllinux builds

[TECH7Fox]

Removes the filter to include musllinux builds for Alpine, which is very popular for containers, and more. In my case I need it specifically for Home Assistant. Tested it and the CI runs fine and includes the additional musllinux wheels.

Was there a reason to originally exclude it?

@jlaine could you take a look at this? Would be very useful since we can't deploy to HA without this.

While I'm not opposed to this as such, this is not a trivial effort. The first step is going to be to make sure there are musllinux wheels for all binary dependencies:

• https://pypi.org/project/av/ This one is going to be hard. It involves building FFmpeg from source, see https://github.com/pyav-org/pyav-ffmpeg/
• https://pypi.org/project/cryptography/
• https://pypi.org/project/google-crc32c/
• https://pypi.org/project/pylibsrtp/

It almost certainly involves producing binary builds of opus and vpx for musllinux:

https://github.com/aiortc/aiortc-codecs

The build system also needs to be updated to fetch the right version of these builds and put them in their own directory.

Finally we need some sort of smoke test to check the wheels are actually functional, or at the very least do not have missing symbols. Currently tests on the wheels are disabled because they took too long to run on all platforms. See #1059

The linting error will go away if you rebase on top of main, which should allow you to view the failures with the wheels.

Thank you for the message. For now I got aiortc successfully building in home-assistant/wheels-custom-integrations#684

So we can use it in HA. But this would still be helpful for others.

I will try to get this working when I have some time.
