Port `app-lua` to use musl

Port app-lua to use musl, the new supported unikraft glibc.

You should create the Makefile and Makefile.uk files.
You can find more information on this on the Unikraft website.
You can find a list of the external libraries the application depends on in the kraft.yaml file, under the libraries: section.
You will need to replace the newlib dependency with musl.
