Handling of $provides in ap

The apkdb as created by aports/db.lua also considers package names specified in $provides:

https://gitlab.alpinelinux.org/alpine/lua-aports/-/blob/master/aports/db.lua#L152

As such, ap subcommands also work on these package names which is somewhat unexpected. For example:

$ ap builddirs -d ~/src/aports/main gnupg
~/src/aports/main/gnupg
~/aports/main/gnupg1

This behaviour currently causes a bug in the GitLab CI script. For example, if the gnupg aport was modified the CI build script will also attempt to rebuild the gnupg1 aport.

I am not sure what the intended behaviour of the ap script is. Maybe the code for considering $provides could be disabled using an option?
