llama : fix signed comparison warning on FreeBSD (#17497)

This ensures correct RLIM_INFINITY handling and compatibility on all platforms (32/64-bit).

    warning: comparison of integers of different signs: 'rlim_t' (aka 'long') and 'size_t' (aka 'unsigned long') [-Wsign-compare]
      488 |         if (suggest && (lock_limit.rlim_max > lock_limit.rlim_cur + size)) {
          |                         ~~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~
