description:
lint: remove grammar conflict for __real__ and __imag__

The rules were redundant since a term can be parenthesized by itself,
there is no need for an extra rule.  The rules for '__real__(term)' and
'__imag__(term)' were never reduced since these cases were handled by
the rules '__real__ term' and '__imag__ term' a few lines above.

No functional change.
