barebox: use lz4 instead of lz4c

lz4c has been considered deprecated by upstream since at least 2018 [1]
and has been disabled by default recently [2].  openSUSE Tumbleweed is
no longer packaging the deprecated version and others will likely
follow.

Going back as far as Ubuntu 16.04/Fedora 25, both lz4 and lz4c are
installed as part of the same package so switching should be safe.
