Label /usr/lib/networkmanager/ like /usr/lib/NetworkManager/

On ArchLinux the directory name of Network Manager in /usr/lib is
written in lowercase but not the files in /usr/bin, /var/lib, etc.

While at it, remove a useless backslash before a minus character.

Label (/var)?/tmp/systemd-private-.../tmp like /tmp

Such directories are used by systemd as private mountpoints for
