Add tcpdump package to set of packages installed

[mayankbh]

It's too useful not to have.

Minor: Move haveged up to be in alphabetical order.

Testing Done:

Built OVA using make build-ova. Deployed using Fusion and verified that tcpdump was installed.

root@haproxy [ ~ ]# tcpdump --help
tcpdump version 4.9.3
libpcap version 1.9.1 (with TPACKET_V3)
OpenSSL 1.0.2x-fips  8 Dec 2020
Usage: tcpdump [-aAbdDefhHIJKlLnNOpqStuUvxX#] [ -B size ] [ -c count ]
                [ -C file_size ] [ -E algo:secret ] [ -F file ] [ -G seconds ]
                [ -i interface ] [ -j tstamptype ] [ -M secret ] [ --number ]
                [ -Q in|out|inout ]
                [ -r file ] [ -s snaplen ] [ --time-stamp-precision precision ]
                [ --immediate-mode ] [ -T type ] [ --version ] [ -V file ]
                [ -w file ] [ -W filecount ] [ -y datalinktype ] [ -z postrotate-command ]
                [ -Z user ] [ expression ]

Making sure random packet captures work

tcpdump -i management
...
6653 packets captured
6881 packets received by filter
224 packets dropped by kernel

Making sure haveged is still present

root@haproxy [ ~ ]# ps -A | grep haveged
  517 ?        00:00:00 haveged
root@haproxy [ ~ ]#
