In some recipes overly-split -dbg packages were merged into PN-dbg.  Unless
there's a very good reason, recipes should have a single -dev and -dbg package.

Pull package from meta-oe to oe-core:
meta-oe commit: bce4dba5546480c8e43c6442959ac7d0a4ef32f6

The libcap-ng library is intended to make programming with posix
capabilities much easier than the traditional libcap library.

It's not a replacement to libcap, it provides different library
(libcap-ng.so) while packages explicitly look for libcap.so. It
could be used by qemu, util-linux, libvirt, audit ...

With adding it to oe-core, the copies from following layers could
be removed:

* meta-oe, meta-selinux, meta-security-framework ...
