ccache.bbclass: use ccache from host distribution

ccache 4.x has hard dependencies on cmake-native (used as
build system) and zstd, which means inserting ccache-native
as DEPENDS into everything creates circular dependencies which
are impossible to break.

ccache 3.x did not have this problem as it used plain makefiles
and an in-tree copy of zlib.
