John Bowler a5b340e20b timepng: fix builds in certain 1.7 configs
Libpng 1.7 supports read without PNG de-interlace, however this means the old
checks on whether contrib/libtests/timepng.c (just checking for sequential read)
are inadequate.  1.7 also provides macros to explicitly turn off png_read_png
and png_read_image, so use these instead.

This "contrib" directory contains contributions which are not necessarily under
the libpng license, although all are open source.  They are not part of
libpng proper and are not used for building the library, although some are used
for testing the library via "make check".
