Fix buffer overflow when setting NETVAR string console variable and ensure servername is within MAXSERVERNAME

See merge request STJr/SRB2!2445

This commit adds a verification before setting the servername console
variable. We now check that it fits within the MAXSERVERNAME length and
we cancel setting it if it doesn't.
Letting the servername be more than MAXSERVERNAME could lead to crashes
when trying to edit the server name from the menu so, we now avoid
those.
