pkgaux writes Package/<name>/depends for every name that a package
provides. If a package provides the name of another real package, it
overwrites the dependencies of that package: dnsmasq-full provides
dnsmasq, so dnsmasq gets the dependencies of dnsmasq-full, among them
nftables-json and libnftnl.
These lists are used for the library dependencies of the prepare
stamp. dnsmasq thus depends on libnftnl without being ordered after it,
and is built again in the build that follows a clean build.
Skip provided names that belong to another real package.
