argp-standalone: fix build issue caused by UCHAR_MAX definition
The issue was simply that the patch from Max Filippov forgot to include <limits.h> to get the definition of UCHAR_MAX. Fixes: http://autobuild.buildroot.org/results/bd1/bd120ada4830fda3db96da945513d4f6f7b2d419/ and lots of similar build failures. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
