  mkfifoat: use new modules for Solaris and BSD bugs
  
  Pick up Solaris 9 and BSD fixes to mkfifo and mknod.  No known
  system has mknodat but broken mknod, so there is no need for
  rpl_mkfifoat or rpl_mknodat.  Split mknodat into its own file.
  
  * m4/mkfifoat.m4 (gl_FUNC_MKFIFOAT): Simplify.
  * lib/mkfifoat.c (mknodat): Split...
  * lib/mknodat.c (mknodat): ...into new file.
  * modules/mkfifoat (Files): Ship new file.
  (Depends-on): Add mkfifo, mknod.
  * modules/mkfifoat-tests (Files): Reuse mkfifo tests.
  (Depends-on): Add symlink.
  * tests/test-mkfifoat.c (main): Enhance test.  Drop portions now
  redundant with test_mkfifo.h.
  (do_mkfifoat, do_mknodat): New helpers.
