Andreas Schneider ce2df481b7 Fix size types ...

This fixes compilation with -Wstrict-overflow=2

with CFLAGS="-O3 -Werror=strict-overflow -Wstrict-overflow=2"
gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10) gives:

config_file.c: In function ‘krb5_config_vget_strings’:
config_file.c:1122:10: warning: assuming signed overflow does not occur when simplifying conditional to constant [-Wstrict-overflow]
     while(nstr--)
          ^
