Giovanni Campagna ac0c7df4a3 keybindings: fix invalid read after a keybinding is removed 
The handler pointer is dangling in MetaKeyBinding until
rebuild_key_binding_table() is run, so we can't dereference it.
Because we only need the flags at ungrab time, store a copy
in the MetaKeyBinding structure.
