Settings: Enable menu key to unlock lockscreen

Remove the "enable widgets" preference properly

779a6aed2c89b17ee11e59710434dac31dfbd7ec removed this preference in
favor of a switch in the CM lock screen section, but failed to do so for
all lock screen types. Remove the broken preference from every possible
lock type to avoid confusing a lot of people (i.e. me) with a broken
toggle.
