alpha/sys/user.h: remove asm/page.h references

[Mike Frysinger <vapier at gentoo dot org>]

newer kernel headers no longer install asm/page.h.  this causes breakage on 
alpha where its sys/user.h header pulls in asm/page.h for PAGE defines.  
attached patch fixes the issue like some other arches have fixed it.
