Refine some public files in xwalk runtime.

The public files under xwalk/runtime/browser should be
located to the correct compiling path and the unused codes
related to Android port in the resource dispatcher host
delegation file should be removed. This fix is to refine
the corresponding files in xwalk runtime.

[Android][SysApss] Fixed getMemoryInfo to support Android 4.0 and below.

1. The original implementation uses an API avaible since API level 16. Change
the implementation to reading file "/proc/meminfo" when the target system
is Android 4.0 and below.
2. The spec http://device-capabilities.sysapps.org/#memory requires to return
byte instead of KB. So change the unit to byte.

[Extensions] Make it possible to export a custom object

Currently the JavaScript shim receives an "export" object which you are supposed
to add properties. But what if you want to export an object created in the shim
instead? This patch adds support for that: now, by assigning it to an object,
the object gets exported at the root of the API namespace instead of the
"export" object.
[Extensions] Add tests for exporting objects in the JavaScript shim

The test verifies if both methods of exporting objects (hanging properties
on the "export" object or assigning it to another object) are working fine.
