kickstart update for patched iso

This commit copies the patch xml metadata
if the patches directory exists in a pxeboot
installation and copies the xml content to the
patch repository at /opt/patching.

* Currently this only works for USB Install.

Test:
Pass: Install via pxeboot and sw-patch query works
