[libvirt] [PATCH v5 4/6] xenconfig: add support for parsing type= xl config entry

[Marek Marczykowski-Górecki]

builder="hvm" is deprecated since Xen 4.10, new syntax is type="hvm" (or
type="pv", which is default). Since the old one is still supported,
still use it when writing native config, so the config will work on
older Xen too (and will also not complicate tests).

"type" option is the only syntax for specifying PVH guest, coming in
next patch.

Changes in v2:
 - fix code style
