Use Fixed-length when drawing percussive events

Previously adding percussive-hits created sustained notes
using the current grid as duration. This allowed to create
overlapping notes with the overlap not being visible.

Most hardware MIDI drumkits do send an immediate note-off event
after each hit (if they send note-offs at all).
Ardour now follows suit and does the same when using the draw/edit tool.
