lcdproc: Fix non x86 platforms on musl

Musl only specifies in/outb for x86/x86. Use the fallback path in case
musl is used.

This should fail compilation during the linking stage but for some reason
does not. Will do if -Werror=implicit-function-declaration is specified.

Fixed up license information.

Other small cleanups.
