Don't run system("touch conf.gtktest") in the AM_PATH_GTK_2_0 macro

Just use the C library instead to create the file. Helps building
using Wine. Not that I think we want to endorse that way to build GTK+
for Windows, proper cross-compiling surely probably more sense, but
accepting this minimal patch doesn't hurt. From bug #590017.
