kernel: Fix kmod-lib-lz4 packaging
The kernel provides two variants of the lz4 compression a normal version
and a high compression mode version. The old kmod-lib-lz4 package
contained the normal version plus one part of the lz4hc version. There
was already code which selected the kmod-lib-lz4hc package which did
not exists.
I split this into 3 packages. kmod-lib-lz4 and kmod-lib-lz4hc for the
normal the and high compression algorithm which contain the specific
code and the kmod-lib-lz4-decompress which contains the common
decompressor.
New we are also packaging lz4hc.ko
