Add accessibility_unittests and chromevox_tests to buildbot config.

accessibility_unittests should run everywhere except iOS. It's small and
very fast.

chromevox_tests is only for Chromium OS.

In iossim, fix default device value for Xcode 6.

The default was "iPhone", but that's not supported in Xcode 6, so use
"iPhone 5" in that case.

Also remove an unnecessary call to |connect| when printing supported
devices on Xcode 6. This call is not needed and just hangs for a few
seconds so remove it (all that's really needed is to load the
CoreSimulation framework.

TEST=With Xcode 6 installed, build iossim then run iossim with no
optional paramters (e.g. out/Debug-iphonesimulator/iossim path/to/my.app

In iossim, use default home directory if no -u override is given.

With Xcode 6, the home directory of the iOS Simulator and iossim
processes must match so that the iOS Simulator can find the SimDevice
object created by iossim. Since the existing behavior of iossim is to
create a new, random, home directory on each run (if no -u value is
specified on the command line), the home directories will be  mismatched
if iossim is launched multiple times without killing the iOS Simulator
in between runs.

The fix here is to only override the home directory in iossim if -u
is specified. Since this will often reuse the default SimDeviceSet
(at ~/Library/Developer/CoreSimulator/Devices), functionality
is also changed to reuse an existing SimDevice if possible (though
iossim will create a SimDevice if necessary).

Flush gcda (code coverage) files manually in iOS Platform Test.

iOS 7 does not call any code at the "end" of an app so flushing should
be performed manually.
