target/imagebuilder: use multi-thread support for xz compression
This speeds up the packing of the imagebuilder a lot:
imagebuilder-T0.tar.xz real 0m25.199s user 2m45.967s sys 0m1.218s
imagebuilder-T1.tar.xz real 2m02.543s user 2m02.418s sys 0m1.653s
imagebuilder-T2.tar.xz real 1m03.684s user 1m59.931s sys 0m0.587s
imagebuilder-T3.tar.xz real 0m48.033s user 2m02.904s sys 0m0.637s
imagebuilder-T4.tar.xz real 0m38.963s user 2m15.521s sys 0m0.783s
imagebuilder-T5.tar.xz real 0m37.994s user 2m21.461s sys 0m0.919s
imagebuilder-T6.tar.xz real 0m39.524s user 2m48.115s sys 0m1.279s
imagebuilder-T7.tar.xz real 0m34.061s user 2m45.097s sys 0m1.174s
imagebuilder-T8.tar.xz real 0m27.286s user 2m55.449s sys 0m1.329s
imagebuilder-T9.tar.xz real 0m25.205s user 2m44.894s sys 0m1.208s
To keep the output reproducible in any case, we enforce a minimum amount
of 2 threads.
