Subject: [PATCH] build: fix provides logic when ABI version is set

Same as for the base package name, when a package has an ABI version,
provide both unversioned provider in addition to one with ABI version
and version.

So for each provide instead of providing only:

$provide$ABI_version=$package_version

now provide:

$provide $provide$ABI_version=$package_version

When a provide ends in a number, the ABI version will be prefixed with
a - sign, e.g.: provide1-0
