Don't cast GTime* to time_t*
Coverity CIDs 16825 and 16826
The glib frontend casts a GTime* to time_t* in _poppler_attachment_new. These
are different sizes on x86_64, so it can result in junk being written to the
succeeding bytes of the PopplerAttachment struct if a PDF's EmbeddedFile dates
do not fit in 32 bits. It's possible to crash Evince when it tries to free an
invalid attachment->checksum pointer.
Attached patch replaces the pointer cast with an assignment.</pre>
