add Zstandard compression support
I changed the style of the hackargs variable in autogen.sh to multiline
because said line was becoming a bit long with the new --with-zstd arg
added.
A previous version of this patch has been running on my two Arch Linux
installations (with an accompanying mkinitcpio patch) for several months
over many kernel updates without any issues.
Any additional testing and/or patch review would of course be appreciated.
