samba: remove ${localstatedir}/log

Fixed do_package error:
WARNING: samba-4.4.2-r0 do_package: FILES contains file '/var/log/samba' which resides under a directory symlink. Please fix the recipe and use the real path for the file.
ERROR: samba-4.4.2-r0 do_package: File './var/log/samba' cannot be packaged into 'samba-base' because its parent directory structure does not exist. One of its parent directories is a symlink whose target directory is not included in the package.
ERROR: samba-4.4.2-r0 do_package: Function failed: populate_packages

It has a file ${sysconfdir}/tmpfiles.d/samba.conf which will create
/var/log/samba when systemd, and volatiles.03_samba when sysvinit.
