Clarify that --net should be used to create a new network namespace
before using a firejail command that needs to be executed inside a
(firejail) network namespace.

Example:

$ firejail --netfilter.print=10000
Switching to pid 10001, the first child process inside the sandbox
Error: the sandbox doesn't use a new network namespace (see --net)

Relates to #6820.
