[PATCH v2] aio_suspend.3: SYNOPSIS: Use 'restrict' in prototypes

[Alejandro Colomar <alx.manpages@gmail.com>]

POSIX does NOT specify aio_suspend() to use 'restrict'.
However, glibc uses 'restrict'.
Users might be surprised by this!  Let's use it here too!

......

.../glibc$ grep_glibc_prototype aio_suspend
rt/aio.h:167:
extern int aio_suspend (const struct aiocb *const __list[], int __nent,
			const struct timespec *__restrict __timeout)
  __nonnull ((1));
.../glibc$

v2:
	- wsfix + srcfix: Avoid breaking the line in the prototype
	- Note the difference between POSIX and glibc in CONFORMING TO.
