gtkmathview: fix build error

When building, I was seeing the following error which this patch fixes:

	../../../src/frontend/common/TemplateElementIterator.hh:46:18: error:
	'valid' was not declared in this scope, and no declarations were found by
	argument-dependent lookup at the point of instantiation [-fpermissive]
