Subject: [PATCH] Fix configure errors when using GTK 2 and ASAN

Memory leaks in the test programs run by configure when using GTK 2
result in configuration failures when using -fsanitize=address in
{CXX,LD}FLAGS, so fix these leaks to allow configuring using
"CXXFLAGS=-fsanitize=address LDFLAGS=-fsanitize=address" together with
--with-gtk=2 (this already worked correctly with the default GTK 3).

Closes https://github.com/wxWidgets/wxWidgets/pull/2001
