cbf0a7c417 Use default xz compression (-6) for raspi2 image
Xz with -0 generated ~35% bigger compressed image.

646a88b5ee Use xz -T4 -0 instead of pxz
Test showed very little difference in file-size between -0 and -9 while
both compression and decompression need much less memory and compression
needs less CPU time for -0.

Supported xz versions before 5.2 also accept the -T4 option but ignore it.

Also depend on xz-utils instead of downloading pxz.
