Fixed undefined behavior in pngvalid.c, undefined because
(png_byte) << shift is undefined if it changes the signed bit
(because png_byte is promoted to int). The libpng exported functions
png_get_uint_32 and png_get_uint_16 handle this. (Bug reported by
David Drysdale as a result of reports from UBSAN in clang 3.8).
This changes pngvalid to use BE random numbers; this used to produce
errors but these should not be fixed as a result of the previous changes.
