bitbake: bb/compress: 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.

Luckily, we're not using any legacy-specific options and, going back as
far as Ubuntu 16.04/Fedora 25, both lz4 and lz4cli are installed as part
of the same package
