commit e9444649f49431a8e203e6e2009a1de05e505007
Author: Alex Kiernan <alex.kiernan at gmail.com>

    systemd: Restore mask and preset targets, fix instance creation
    
    Ensure that anyone who sets SYSTEMD_AUTO_ENABLE_${PN} = "mask" (or
    "preset") retains the previous behaviour. In addition fix "enable" so it
    can (again) create instance units out of templates.
    
    Remove over-zealous quoting of SYSTEMD_SERVICE_ESCAPED as it's already
    safely escaped (and can be multiple arguments).
