Modern distros like Fedora have started to compress their
kernel module files, so we can't simply read the file contents
and load the module. We have to first do a decompression step,
as the kernel won't do that itself.  While Fedora uses lzma,
upstream kernels are also capable of using gzip.

This links in the lzma and gzip libraries to handle
decompression. NB the static versions of lzma/gzip
are required since libvirt-sandbox-init-qemu must be
statically linked.
