Move Android user agent generation to native code

Gets rid of a pathway that forced us to set the user agent
from the Java side, replacing it with one that's entirely
native.  Functions have been added to base to allow accessing
information about the device and Android build, while the
user agent generation code was moved to the webkit_glue
namespace.
