Fix a crash in png_convert_from_time_t with an invalid time_t argument

This bug was found by FUTAG, a program for generating automated
fuzz-targets of libraries.

TODO:
Implement a safe function, alternative to png_convert_from_time_t,
which takes a png_ptr argument and raises a png_error if the time_t
argument is invalid.
