cli: fix incorrect hookopts field check in chain dump

[Nepomuk5665]

Summary

• Fix copy-paste bug where BF_HOOKOPTS_FAMILY was checked instead of BF_HOOKOPTS_PRIORITIES when printing priorities
• The bug caused priorities to not be printed when only BF_HOOKOPTS_PRIORITIES was set
• The bug also caused priorities to be printed with potentially invalid values when only BF_HOOKOPTS_FAMILY was set

Bug Details

In bfc_chain_dump(), the condition for printing the priorities field incorrectly checked for BF_HOOKOPTS_FAMILY:

// Before (incorrect - copy-paste error)
if (bf_hookopts_is_used(hookopts, BF_HOOKOPTS_FAMILY)) {
    (void)fprintf(stdout, "%spriorities=%d-%d", ...);
    ...
}

// After (correct)
if (bf_hookopts_is_used(hookopts, BF_HOOKOPTS_PRIORITIES)) {
    (void)fprintf(stdout, "%spriorities=%d-%d", ...);
    ...
}

This was clearly a copy-paste error from the preceding block that checks BF_HOOKOPTS_FAMILY for the family field.

Testing

• Code inspection confirms the fix matches the enum definition in hook.h
