feat: validate Ubuntu version if launching firefox (#3156)

Browse Source 
The original plan was to rnu some checks against libc version the
binary is compiled with, but these turn out to be a little complicated:
parsing out libc version from both static binary and host system
requires text processing, and it's hard to make sure it works reliably
across distributions.

Instead, let's start with a very particular check against running
Firefox on Ubuntu 16.04.
