Squert: improve consistency of username handling

[dougburks]

Please test/verify as follows:

• create a VM using the new 16.04.6.2 ISO

• run so-import-pcap just to get a quick setup going:

  sudo so-import-pcap /opt/samples/markofu/outbound.pcap

• verify that Squert is case-sensitive for username but Kibana, CapMe, and Sguil are not

• snapshot the VM

• add the test PPA:

  sudo add-apt-repository -y ppa:securityonion/test

• install updates:

  sudo soup

• verify that Squert now matches username same as Kibana, CapMe, and Sguil

• verify no regressions

• anything else we missed?

Thanks in advance for your time and effort!

Confirmed username works across all apps with both upper and lowercase.

Thanks, Wes
