www/foswiki: remove redundant escape

= does not need to be escaped in this context; bug #229925 will make this
escape as well as the escape of most ordinary characters an error to reduce
friction when some of these ordinary characters are later granted special
GNU-extended behavior.

No functional change, no need to bump PORTREVISION.
