radsniff: Fix buffer overruns

Divide by the element size when checking for circular buffer wrap in
rs_response_to_pcap and rs_request_to_pcap.

The following Coverity errors were reported for the defect.

Error: OVERRUN (CWE-119):
freeradius-server-3.0.4rc2/src/main/radsniff.c:934: illegal_address:
"&request->capture[80UL]" evaluates to an address that is at byte offset
1280 of an array of 80 bytes.

Error: SIZEOF_MISMATCH (CWE-398):
freeradius-server-3.0.4rc2/src/main/radsniff.c:934:
suspicious_pointer_arithmetic: Adding "80UL /* sizeof (request->capture)
*/" to pointer "request->capture" of type "rs_capture_t [5]" is
suspicious because adding an integral value to this pointer
automatically scales that value by the size, 16 bytes, of the pointed-to
type, "rs_capture_t".  Most likely, you intended to use the number of
elements in "request->capture" rather than its size in bytes.
