Fix setting value comparison issue that caused some settings to look the
	same when they were really different (rh #464417)

	* libnm-util/nm-param-spec-specialized.c
		- (type_is_fixed_size): return fundamental size of the fixed type too
		- (nm_gvalues_compare_collection): use the fundamental fixed type size
			in the comparison so that the _entire_ fixed type collection gets
			compared rather than just the first 'len1' bytes
