testing/xen: add xen 4.1.2

Build full Xen distribution.

Changes since v4:

 * Removed "opts=" from xencommons init script.

 * Backported upstream patch to boot Syslinux PV-DomUs with pygrub
   (allows booting Alpine PV-DomUs).

Changes since v3:

 * Added bash as a runtime dependency, since some hotplug scripts
   use that instead of /bin/sh.

Changes since v2:

 * Clean and updated init scripts to be as similar as possible to
   upstream version.

Changes since v1:

 * Removed net from xencommons dependencies and added udev.

+pygrub: fix extlinux parsing
+
+pygrub was unable to parse extlinux config files correctly, exactly
+the ones like:
+
+LABEL grsec
+  KERNEL vmlinuz-3.0.10-grsec
+  APPEND initrd=initramfs-3.0.10-grsec
+root=UUID=cfd4a7b4-8c40-4025-b877-8205f1c622ee
+modules=sd-mod,usb-storage,ext4 xen quiet
+
+This patch fixes it, adding a new case when parsing the "append" line,
+that searches for the initrd image.
