META_MODE: Remove DEP_RELDIR from Makefile.depend files.

This has not been needed since r284171 in projects/bmake.

Add META_MODE support.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

Reorganize targets/pseudo/userland

This target mainly exists to help check things build.
Eventually targets that build real packages or images will be more
important.
As such move the pseudo targets that only exist for the benefit of
'userland' to under it.

Rename pkgs to more generic targets (that's what they are)
