Bug description:
[Impact]

 * Bogus keycode messages produced by the kernel / user annoyance
 * rfkill keyboard shortcuts not working as intended on some Dell machines

[Test Case]

 * check that there are no spurious kernel messages about unknown keys
in journalctl upon RFKill key presses

 * check that RFKill key presses work correctly and kill/restore RF
capabilities

[Regression Potential]

 * The change is scoped to particular SKUs and thus should only affect them
 * It is related to matching gsd support, which is in-place on xenial and up

[Solution]
Cherrypick upstream commit https://github.com/systemd/systemd/commit/cab01e9ecf1c69656785e64f5fc94cd4ed09e57f

[Original Bug report]

RFKill key produces these messages in kernel log:

dell_wmi: Unknown key with type 0x0010 and code 0xe008 pressed

This key code is a notification and should be added as KEY_IGNORE
