Doc: simplify example for unpure-pure containers

Use of ly:event-property only confuses matters.  Squares are never used.

Draw circles unconditionally, make them empty inside (which would make
the wrong output easier to discern) and name the macros roundNotes and
smartRoundNotes.  No need to define a separate Scheme function, a
one-line lambda in stencil definition is enough.

Don't remove Stem_engraver, just use whole notes and adjust the time
signature.
