[PATCH] Mark VMSPLIT EMBEDDED

Running abnormal VM splits causes weird problems - people can set non-standard
splits by accident, then lots of time gets wasted diagnosing it - see the long
"[stable] 2.6.16.6 breaks java...  sort of" email thread.

So we need to make this option harder to set.  Use CONFIG_EMBEDDED for this.

CONFIG_EMBEDDED isn't really the right thing to use, but there's nothing else
obvious and avoiding these problems is more important than Kconfig purity.
