[PATCH] ipv6: default IPV6_SIT to m

[Alyssa Ross <hi@alyssa.is>]

This basically defaulted to m until recently, since IPV6 defaulted to
m.  Since IPV6 was changed to a boolean with a default of y, IPV6_SIT
started defaulting to built-in as well.  This results in a surprise
sit0 device by default for defconfig (and defconfig-derived config)
users at boot.  For me, this broke an (admittedly non-robust) script.
Preserve the behaviour of most configs by avoiding building this
module, that's probably overall seldom used compared to IPv6 as a
whole, into the kernel.
