[OE-core] [PATCH] image_types: adjust default level of XZ compression

[Alexander D. Kanevskiy]

XZ extreme compression method usually uses a lot more CPU time with not
that often big saving on space. Same goes with -6 level of compression.
Compression level -3 usually the best balance for time/size, especially
on big images.
