Remove APT specific dependency installation scripts

I'm running Void Linux with musl libc, and the Node runtime provided by n is built for GNU libc.

Also, same goes for the AppImage release, which also doesn't support musl libc.

And theres also the thing about libraries in musl being under /usr/lib and not /usr/lib/x86_64-linux-gnu.

EDIT: It would be more better to avoid APT specific install commands.
