Fix altreloc remap, always NOP-fill padding bytes.
...
This fixes a very rare (requires that an altreloc span two pages) kernel
crash where it writes past the region that was remapped as RWX, thus
triggering an in-kernel "wrote without write access" page fault.
Additionally, this fixes the logic for unavailable features. It fixes
the short-circuit that would forget to remap the memory back from RWX to
R-X. NOP bytes are also now replaced with multi-byte NOP regardless of
whether the CPU supports the given feature.
