kernel-build.eclass: compress xz/zstd in parallel
Note that this will only take effect if compressing
modules with xz or zstd (COMPRESS_MODULE_XZ is set or
COMPRESS_MODULE_ZSTD is set respectively)
... or if compiling the kernel with xz or zstd (COMPRESS_KERNEL_XZ
or COMPRESS_KERNEL_ZSTD is set respectiely).
