[BZ #19239] Don't include sys/sysmacros.h from sys/types.h.

Browse Source 
This completes the deprecation and removal of this inclusion, which
was begun in the 2.25 release.

	* posix/sys/types.h: Don't include sys/sysmacros.h.
	* misc/sys/sysmacros.h: Remove the conditional deprecation
	warnings for the macros defined by this header.
