log: fix log_append_stderr()

Log output currently looks like this:

	lxc-copy: debbdev/lxcdir.c: dir_clonepaths: 45 directories cannot be snapshotted.  Try aufs or overlayfs.

we rather want it to be:

	lxc-copy: deb: bdev/lxcdir.c: dir_clonepaths: 45 directories cannot be snapshotted.  Try aufs or overlayfs.
