[PATCH 6/6] fs: squashfs: Enable squashfs XZ support when XZ is enabled

[Sascha Hauer]

XZ support itself is much more expensive than the squashfs XZ wrapper,
so it makes sense to just compile XZ support into barebox when XZ
support is available. No need to ask the user for it.

-	  XZ is not the standard compression used in Squashfs and so most
-	  file systems will be readable without selecting this option.
