VMM: Touch up ros/vmx.h's includes (XCC)

We need those includes to compile.  I ran into this while making a new C
file.

We also need to get rid of the rdmsr macros, since userspace should never
even call that.  Right now, you could get a compilation error with those
macros since read_msr() isn't in any user headers.

Reinstall your kernel headers
