Apply patches to fix CVE-2018-6954
NVD description from https://nvd.nist.gov/vuln/detail/CVE-2018-6954
systemd-tmpfiles in systemd through 237 mishandles symlinks present in
non-terminal path components, which allows local users to obtain
ownership of arbitrary files via vectors involving creation of a
directory and a file under that directory, and later replacing that
directory with a symlink. This occurs even if the fs.protected_symlinks
sysctl is turned on.
Patches from systemd_237-3ubuntu10.13.debian.
These patches shouldn't be required on newer OE releases since they use
systemd v239 or higher.
