[Packaging] Prefer pkgconfig(package) in BuildRequires when possible.

The recommended way to depend on packages is to use BuildRequires:
pkgconfig(foo) instead of explicitly using BuildRequires: libfoo-devel.

Use that where possible, and remove a duplicate entry for
pkgmgr-info-parser-devel, which already has a pkgconfig() entry.
