pkgbase: use -dev,-dbg instead of -development,-debug

-development is long and awkward, and is also inconsistent with prior art
from the Linux world, which uses -dev (Debian) or -devel (Red Hat). Follow
the Debian convention, and similarly for debug info packages.

Also remove redundant pkgbase development tag from includes. We already tag
include files with package=runtime,dev; there is no need to separately tag
them as dev.
