[OE-core] [PATCH][for-denzil 8/8] image_types.bbclass: Default XZ_COMPRESSION_LEVEL to -e -6

[Koen Kooi]

From: Andrei Gherzan <andrei at gherzan.ro>

Having XZ_COMPRESSION_LEVEL on -e -9 and -T 0 will make xz eat more
than 6Gb memory. Reduce this to -6 to make xz to use about 471Mb
on the tested machine.
