client: honor IPv4 header length in GPRS filter
The GPRS-NS/BSSGP filter assumed a fixed 20-byte IPv4 header (IP_LEN)
when locating the UDP header and payload. When the captured packet
carries IPv4 options (ip_hl > 5), udp_data/payload_data pointed into
the middle of the headers and check_gprs() parsed garbage, classifying
packets incorrectly.
Use the actual header length from ip_hl, reject malformed headers
(ip_hl < 5), and re-validate that the larger headers fit within the
captured length before computing the payload.
