Subject: [PATCH] Fix test sleep on iOS.

[ Merge of http://go/wvgerrit/117203 ]

clock_settime isn't available on iOS (even though settimeofday is).  But
we can't change the system time on iOS anyway, so this just disallows
iOS.

Bug: 182058081
Test: WV unit/integration tests
Change-Id: I96e5b6634803bd4e6aaf5cc6d64f4441296247d4
