base64: always treat input in binary mode

Necessary for cygwin.  Technically, this patch is not correct,
in that it clobbers O_APPEND, but it is no different than any
other use of xfreopen to force binary mode, so all such uses
should be fixed at once in a later patch.

* src/base64.c (main): Open input in binary mode.
* THANKS: Update.
