Keyguard: Set WIDGET_CATEGORY_KEYGUARD when AppWidgetHostView is created

Allows the default lockscreen widget to inherit the keyguard widget
host category.  Without this, only widgets added through
KeyguardActivityLauncher are assigned the correct
OPTION_APPWIDGET_HOST_CATEGORY.

Keyguard: fix not shown overlay widgets from system

google derp....due that if widgets are disabled current AOSP
code just add the default widget. Then checkAppWidgetConsistency()
detects a widget which was added and the complete method is non op.
Whatever lets handle the whole process over checkAppWidgetConsistency()
on widget disabled it tries to bind the default widget over overlay if
this is without sucess it falls back to the system one.
Safemode falls always to the system one

This fixes as well an issue that the saved default id in LockPatternUtils
is not reseted back to default if all widgets were deleted from the user.
Based on an old patch from danesh. Thanks for the
suggestion
