wdctl: mark flags field as unsigned long

This is required by string_to_bitmask().
The previous cast failed on s390x with the following warning:

In function 'string_to_bitmask',
    inlined from 'string_to_bitmask' at lib/strutils.c:802:5,
    inlined from 'main' at sys-utils/wdctl.c:770:8:
lib/strutils.c:829:23: error: write of 64-bit data outside the bound of destination object, data truncated into 32-bit [-Werror=extra]
  829 |                 *mask |= flag;
