[PATCH 3/3] cmake-native: rationalise system/internal library dependencies

[Ross Burton <ross.burton@intel.com>]

By default cmake will auto-detect if a library is present on the host and if it
isn't present will use an internal fork.  For some libraries using the internal
fork is preferable as it can be built with less dependencies, but for others
we're either already building it or the impact of building it is comparable to
internal build.

Continue to use the internal fork of libarchive as our libarchive-native has a
large number of build dependencies.  Using the internal libarchive means that
system bzip2 and zlib must be used.

Explicitly use the internal fork of jsoncpp as we don't have this in oe-core.

Explicitly depend on curl-native, expat-native, and xz-native to ensure these
dependencies are not floating.  curl-native is a non-trivial dependency but is
comparable to building the internal fork, so there's no reason to build it
twice.

Change bzip2-native to bzip2-replacement-native as bzip2-native is
ASSUME_PROVIDED.
