BUILD: quic: 32-bits compilation issue with %zu in quic_rx_pkts_del()

This issue arrived with this commit:
    1dbeb35f8 MINOR: quic: Add new traces about by connection RX buffer handling

and revealed by the GH CI as follows:

   src/quic_conn.c: In function ‘quic_rx_pkts_del’:
    include/haproxy/trace.h:134:65: error: format ‘%zu’ expects argument of type ‘size_t’,
    but argument 6 has type ‘uint64_t’ {aka ‘long long unsigned int’} [-Werror=format=]
    _msg_len = snprintf(_msg, sizeof(_msg), (fmt), ##args);

Replace all %zu printf integer format by %llu.

Must be backported to 2.7 where the previous is supposed to be backported.
