Normalize names of some source files

Most tdep/nat files are named:

  <cpu>-<os>-tdep.c
  <cpu>-<os>-nat.c

A few files do not respect this scheme.  This patch renames them so that
they are consistent with the rest of the files.  It builds fine with
--enable-targets=all, but that doesn't test the nat files.  I can only
hope that my grep skill is good enough.
