ci: run tests in alpine vm

Alpine Linux uses musl libc so now accel-ppp is tested under musl

Currently, Alpine Linux doesn't provide a link to the latest stable version
so direct link to Alpine 3.20 is used

Improved musl support might be used to run on platforms like openwrt
without additional patches
