Plug leak in the alphamap test.

The images are being created with non-NULL data, so we have to free it
outselves. This is important because the Cygwin tinderbox is running
out of memory and produces this:

    mmap failed on 20000 1507328
    mmap failed on 40000 1507328
    mmap failed on 20000 1507328
