[Impact]

After upgrading from 16.04 to 18.04, users are unable to type a | or >
in their virtual machines when accessing them via vnc.  This happened
because upstream added a key to the keymap that can also produce these
symbols and exists only on European keyboards, but it uses different
modifier keys to produce these symbols so trying to type a | or a >
results in a < instead.  Simply removing this new non-existent scan code
from the keymap resolves the issue.

[Test Case]

Start a virtual machine and connect to it via vnc.  I am using
"tightvnc" on Windows, and upstream indicated that some vnc clients send
the raw scan code instead of keysyms, in which case this issue would not
arise.

[Regression Potential]

There should be no regression potential for actual en-us keyboards since
this key does not exist.  European keyboards may be unable to use this
other key they have unless they set the correct keymap, but all of its
symbols are duplicates from other keys on the keyboard, rendering it
fully redundant.

[Original Description]

I tried booting some Ubuntu images today on my Xen server where I use
VNC to remotely access the VM, and am unable to type a | ( pipe ).  I
opened the keyboard layout utility and when I press the \ key, it
recognizes it, but when I hold shift and press the key, it claims that I
am pressing some key between left shift and Z that does not actually
exist on US keyboards, and that types a > instead.

This did not used to happen, and probably started when I upgraded the
server from 16.04 to 18.04 a while back and I just haven't been testing
VMs since then.
