[OE-core] [PATCH] package.bbclass: add PRIVATE_LIBS_ALL

[Alexander Kanavin]

PRIVATE_LIBS is used to exclude 'private' libraries from getting added to
automatic runtime dependency resolution. That variable has to list
all libraries by name which becomes a maintenance issue if the list
of such libraries frequently changes, or is very large.

PRIVATE_LIBS_ALL allows declaring all libraries private, either
for a specific target package (e.g. -ptest), or for all packages
produced by a recipe.
