Use sysroot for chromeos builds

Previously the sysroot was only being used for
non-chromeos linux builds because it lacked
certain packages.

CLOCK_REALTIME_ALARM is not defined by bits/time.h
in wheezy so all use of this macro must be conditionalized.

gn: libssl is now only included in the build if
use_openssl is not set which matches the gyp logic.

Are you planning to land this? The Win CQ failure was probably a flake.

The problem here is that that  linux_chromium_chromeos_rel_ng  and  
linux_chromium_chromeos_ozone_rel_ng failures are real.

Basically the chromeos build links against libffi from the sysroot which is
libffi5.   The building of the binaries works find but when we try to run tests
the bots don't have libffi5 installed.  All the bots have libffi6.   I think the
solution is to wait until we update the sysroot to jessie (from the current
wheezy) at which point we can land this (since then the sysroot and the bots
will both have libffi6).

If you want to land this before that time you'll need to make the libffi linking
somehow conditional of open it at runtime in dlopen.

+thestig since he can probably help out with landing this once the jessie update
lands.

I'm going on leave for 6 months so probably won't be around to land this change.
