libxml2: add -dev and -utils packages (closes #8591)

This introduces a libxml2-dev package which contains most stuff
required for developing against libxml2 (on the target), and
the libxml2-utils package which contains the xmllint and xmlcatalog
command line binaries which are provided by libxml2.
