Checking in CL http://www.codereview.chromium.org/2836058 on behalf of zbehan@:

chrome: create an option for using libcros provided by the system; fix all
includes referring to libcros to not include third_party/

* Headers fix is needed to support using system libcros (installed to /usr/include)

* All includes are "", and therefore a local variant in third_party/cros/ is
always preferred, but system will also get picked up as a secondary target

* Fixed chrome/browser/chromeos/cros/synaptics_library.h comments to better
reflect the header placement

* Added a variable system_libcros defaulting to 0
* Gotten rid of duplicate cros_api.gyp
* Changed both places to either link against cros_api or libcrosapi

TEST=build in the following scenarios:
1) libcros not installed, libcros sources in third_party/, !defined system_libcros
- sucess
2) installed libcros, put #error into /usr/include/cros/chromeos_cros_api.h, repeat 1)
- success
3) BUILD_DEFINES+=system_libcros=1, removed libcros from third_party, repeat 2)
- fail (on #error in chromeos_cros_api.h)
4) Installed clean libcros, repeat 3)
- success
