[oe] [meta-systemd][PATCH] systemd: Add patch so we can compile without xz.

[Martin Ertsaas]

A compilation bug in systemd is fixed by this patch. journal-verify.c calls uncompress_blob, in
uncompress.c. uncompress.c is, however, not compiled if you don't compile with xz support. To avoid
GPLv3, one have to turn of this support in systemd, which in turn will cause systemd to fail during linking,
as there is no definition of compress_blob.
