[updated patch] fix build error for graphics/sane-backends on Linux

[Matthias Ferdinand <mf+ml.tech-pkg%netzwerkagentursaarland.de@localhost>]

Hi,

with the current version of patch-sanei_sanei__ir.c removes an 
   #include <values.h>

On NetBSD 6, this does not hurt, but on Linux, now the definitions of
INT_MIN and DBL_MIN are missing.

Attached is an updated patch with instead replaces <values.h> with
<limits.h> and <float.h>. Fixes build on Linux, apparently does not hurt
on NetBSD 6.

Regards
Matthias Ferdinand
