left4me: drop +sv_lan 0 from srcds ExecStart

Browse source 
The original LAN-mode rejection turned out to be a downstream cascade
from Steam SDK init failure (.steam dir invisible + cpu.cpp assert
on hidden /proc/cpuinfo) — fixed in subsequent commits by binding
/var/lib/left4me/.steam + /opt/left4me/steam back through
TemporaryFileSystem and dropping ProcSubset=pid. With Steam master-
server registration now succeeding ("Connection to Steam servers
successful. VAC secure mode is activated."), the server defaults to
internet mode (sv_lan=0) on its own.

Drop the explicit override. If LAN-mode rejection ever recurs the
fix is to identify the upstream Steam-registration issue, not to
re-set this cvar.
