[Buildroot] [PATCH 0 of 3] infra: misc. changes related to pkgparentdir

[Thomas De Schampheleire]

This series was driven by the observation that the 'Patching' message
contained a double slash which annoyed me:

>>> host-lzop 1.03 Patching package//lzop

While fixing this (pkgparentdir change), I bumped into FOO_DIR_PREFIX which
had an incorrect default, and the realization that the Patching message
didn't really need that directory anyway.
