rc.d/linux runs unconditionally

[Michael Butler]

In rc.d/sysvipc we see ..

name="sysvipc"
desc="Load SysV IPC modules"
rcvar="sysvipc_enable"
start_cmd="${name}_start"

 .. so it won't try to run without explicitly setting sysvipc_enable in
/etc/rc.conf.

However in rc.d/linux, we have only ..

name="linux"
desc="Enable Linux ABI"
start_cmd="${name}_start"

 .. which causes it to try to load the linux modules unconditionally
even when I don't want them,
