unistd.h: Declare SUSv3 functions unconditionally

["Shaun Jackman" <sjackman at gmail dot com>]

This patch declares a number of SUSv3 functions found in sys/unistd.h
unconditionally. It also changes the prototype of usleep and sync to
match SUSv3. Does any target need to override the standard prototype,
or can this be fixed globally?

Cheers,
Shaun

	* libc/include/sys/unistd.h (ftruncate, truncate, ualarm, usleep,
	gethostname, mktemp, sync): Declare these SUSv3 functions
	unconditionally.
	(usleep): Change the prototype to match SUSv3.
	(sync) [!__rtems__]: Ditto.
