prebuild: add eudev-dev to Alpine musl apk install

The usb npm package (used by @podkit/ipod-firmware since e825ee1) has a
node-gyp postinstall that compiles libusb against libudev. Alpine ships
the udev headers via the eudev-dev apk package; without it, bun install
fails on the usb package's native build with "libudev.h: No such file".

Same pre-existing musl regression class as the cmake fix in 8c9239d —
glibc and darwin runners already have udev headers available.
