George Sapkin 5ed650acbf build: add support for virtual provides ...

Allow defining virtual provides using the PROVIDES field by prefixing
them with @, e.g.:

PROVIDES:=@ca-certs

Virtual provides don't own the provided name and multiple packages with
the same virtual provides can be installed side-by-side. Packages must
still take care not to override each other's files.

Add an implicit self-provide to packages. apk can't handle self
provides, be it versioned or virtual, so opt for a suffix instead. This
allows several variants to provide the same virtual package without
adding extra provides to the default one, e.g. wget implicitly provides
wget-any and is marked as default, so wget-ssl can explicitly provide
@wget-any as well.

Filter out virtual provides when generating metadata.

Filter out virtual provides prefix and self provide where appropriate.
