CONTRIB: halog: fix issue with array of type char

I just noticed this in the windows build after moving the file to dev/:

   In file included from include/import/ist.h:32,
                   from include/haproxy/connection-t.h:32,
                   from dev/flags/flags.c:5:
  dev/flags/flags.c: In function `main':
  dev/flags/flags.c:442:20: error: array subscript has type `char' [-Werror=char-subscripts]
    442 |           (isalnum(*err) && toupper(*err) != 'U' && toupper(*err) != 'L'))
        |                    ^~~~
    LD      haproxy
  cc1: all warnings being treated as errors
  make: *** [Makefile:932: dev/flags/flags.o] Error 1
  make: *** Waiting for unfinished jobs....
  Error: Process completed with exit code 2.

Let's just cast it to uchar as is done everywhere else.
