Add XML patching bitbake class.

This commit adds a new obmc-xmlpatch class that can be
inherited in a recipe to provide a do_patch task to patch XML
files.  The patch files are themselves XML, and must end in
.patch.xml for do_patch to find them.

This commit also includes Palmetto patches specified in
palmetto.xml.patch.xml that are required to build the system
inventory.
