Lots of valgrind errors in gdi32/tests/font.c

[Dan Kegel]

Today's valgrind run shows a bunch more valgrind warnings in gdi32/tests/font.c:

e.g.

I don't think these are actually new; errors like them have
been around, they just got triggered more with a new test
that was added.   It always worries me when heap
routines start showing up in valgrind dumps, though;
it'd be nice if somebody could take a look at this.
