    security/olm: fix build with clang 19
    
    Clang 19 has become more strict about assigning to const variables,
    resulting in an error similar to:
    
      /wrkdirs/usr/ports/security/olm/work/olm-6d767aaf29bdf15571c2ef4d3f8f9e953de03733/include/olm/list.hh:106:13: error: cannot assign to variable 'other_pos' with const-qualified type 'T *const'
        106 |             ++other_pos;
            |             ^ ~~~~~~~~~
      /wrkdirs/usr/ports/security/olm/work/olm-6d767aaf29bdf15571c2ef4d3f8f9e953de03733/include/olm/list.hh:102:19: note: variable 'other_pos' declared const here
        102 |         T * const other_pos = other._data;
            |         ~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~
    
    In this case, it looks like a typo: "T * const" means that the pointer
    itself is const, thus it cannot be incremented. Instead, this should be
    "T const *" (spelled alternatively as "const T *"), which means that the
    object pointed to is const, not the pointer itself.
