Revert "Remove second call to write_eXIf"

Browse Source 
The second call to png_write_eXIf should not have been removed.

The first call to png_write_eXIf is for writing the eXIf chunk that is
positioned before IDAT, while the second call is for writing the eXIf
chunk that is positioned after IDAT.

TODO:
Implement a correct fix which consists in ensuring that there are no
eXIf chunks simultaneously before and after IDAT.

This reverts commit cd03aaf7bf0e0c748b8c6cb34a56b402b40d61d0.
