category/port: Package name dependencies do not support globbing.

5.9.9 of the Porters Handbook defines the use of pkgname/version
dependencies which does not include globbing. Incidentally
pkg info is used by the ports framework which does support it
but external tools, like Poudriere, don't expect this.

None of these needed globbing. If there is a good reason beyond
convenience for the feature then it needs to be documented and
tools updated.
