Again, move stuff which shouldn't be visible inside (mostly already existing)
#ifdef __KERNEL__.

This fixes a bunch of mislabelled and unlabelled #endifs in unistd.h and also
cleans that up to conform with what's visible on other architectures, since
the minimal fix for the error reported about would have involved a more
intrusive patch, renesting other ifdefs.
