While this is not verified by icecat devs, I think this is the desired
behaviour, to prevent others from fingerprinting you as a GNU/Linux
user. For example, tor browser also reports the user agent as
'Windows NT 6.1'.

To change the (reported) user agent, you can either use
random-agent-spoofer to change user agent perodically or User Agent
Switcher to change to a particular user agent.
