[sql] Enable HAVE_USLEEP for more platforms.

[sql] Enable HAVE_USLEEP for more platforms.

HAVE_USLEEP affects SQLite's sleep implementation, which is used when
SQLite waits for a lock to clear.  Browser databases are generally
uncontended, but this case could happen for WebDatabase in the renderer.

Michael, you may remember this from the Gears days.  I don't think it actually
matters for Chromium, mostly, but I do think it's wrong as-is.

Yaron on the CC line because of the original Android CL
(https://chromiumcodereview.appspot.com/10829062), but he's OOO, so not
expecting any response.

[I was 100% certain I sent this to you earlier, but apparently autocomplete
demolished me.]

Sigh.  I have no idea what this is trying to tell me, there are system-related
errors like execvp and starting up a server, but I can't think of any way that
could relate to this CL.  I'm going to sync up my client and re-upload and cross
my fingers and hope the third time is the charm.
