pkgconf: add recipe

pkgconf is a better replacement for pkg-config. Fedora 26 replaces the
system pkg-config implementation with pkgconf because it "provides better
support for handling .pc files and a stable library ABI/API for integrating
into applications." and is actively maintained, unlike pkg-config.

pkgconf aims to offer many improvements over pkg-config such as faster/more
efficient dependency resolver which "allows for the user to more conservatively
link their binaries -- which may be helpful in some environments, such as when
prelink(1) is being used.

pkgconf also aims to provide a more complete implementation of pkg-config.
The features most likely to benefit the Yocto Project build system are the
faster/more efficient dependency resolution and linker flag optimisation.

Move pkgconf recipe to oe-core from meta-pkgconf:
