BUILD: quic: 32bits build broken by wrong integer conversions for printf()

Since these commits the 32bits build is broken due to several errors as follow:

CC      src/quic_cli.o
src/quic_cli.c: In function ‘dump_quic_full’:
src/quic_cli.c:285:94: error: format ‘%ld’ expects argument of type ‘long int’,
        but argument 5 has type ‘uint64_t’ {aka ‘long long unsigned int’} [-Werror=format=]

      |                                                                 uint64_t {aka long long unsigned int}

Replace several %ld by %llu with ull as printf conversion in quic_clic.c and a
%ld by %lld with (long long) as printf conversion in quic_cc_cubic.c.

Thank you to Ilya (@chipitsine) for having reported this issue in GH #2689.
