ioctlsort: rewrite build rules using noinst_PROGRAMS

* linux/ioctlsort.c: Rename to ioctlsort.c
* Makefile.am (EXTRA_DIST): Rename linux/ioctlsort.c to ioctlsort.c.
[MAINTAINER_MODE] (noinst_PROGRAMS): Add ioctlsort.
(ioctlsort_SOURCES): Add ioctlsort.c.
(nodist_ioctlsort_SOURCES): Add ioctls.h and ioctldefs.h.
(CLEANFILES): Add $(nodist_ioctlsort_SOURCES).
(ioctlsort.$(OBJEXT)): Likewise.
(ioctlsort): Remove.
