Since we merged the xattrs support, Lix cannot build anymore on store backed by ZFS datasets without acltype=posixacl.

This surfaces as:

building '/nix/store/4k10hrr912jib3w2hxdxdlcc3a8y068x-xattrs-under-directory-output.drv'...
setfacl: /nix/store/afqli2a47b29cc6lhz50yhhpnnzvcn79-xattrs-under-directory-output/test: Not supported
error: builder for '/nix/store/4k10hrr912jib3w2hxdxdlcc3a8y068x-xattrs-under-directory-output.drv' failed with exit code 1

We should probably improve the detection code for ACL/xattrs support.
