No need for WTAP_ERR_CANT_READ.
Unlike the standard I/O routines, the code we introduced that supports
fast random seeking on gzipped files will always supply some specific
error code for read errors, so we don't need WTAP_ERR_CANT_READ.
Add WTAP_ERR_CANT_WRITE for writing, as we're still using the standard
I/O routines for that. Set errno to WTAP_ERR_CANT_WRITE before calling
fwrite() in wtap_dump_file_write(), so that it's used if fwrite() fails
without setting errno.
