systemd: Modify legacy.conf to have 775 as file permission for /run/lock

UUCP (cu, uux, uu*) attempts to create locks in /run/lock and it
fails. It fails because the current permission of the directory is
0755 but the binary is owned by uucp:root. Modify the legacy.conf
and change the permission to 0775.
