[OE-core] [PATCH] populate_sdk_base: use xz -T instead of pixz

[Ross Burton]

xz has native support for threaded compression now and SDK creation was the only
part of oe-core which is using pixz instead of xz.

Not only does this remove pixz-native from the SDK dependencies, but in my
limited testing xz -T0 is slightly faster and produces smaller archives than
pixz for the same input.
