Make 'xwalkctl' Tizen-only

SSIA. Crosswalk on desktop does not need xwalkctl, as it does not
provide application management.
[Tizen] Reword Crosswalk's summary in the spec file.

rpmlint currently complains about Crosswalk's Summary entry in its spec
file:

  W: name-repeated-in-summary C Crosswalk
  The name of the package is repeated in its summary. This is often
  redundant information and looks silly in various programs' output.
  Make the summary brief and to the point without including redundant
  information in it.

Follow the suggestion and remove "Crosswalk" from the text.

Remove application storage from the desktop code path

Remove application storage from the desktop code path
(make it Tizen-only). The AppliactionServiceTizen object
was added to own the application storage.

This patch also encapsulates application launching within
the ApplicationService object, and contains multiple code
cleanups.

[Android] Rewrite generate_xwalk_core_library_aar.py.

The previous version was horribly bloated and broken. The main
issue (which is blocking XWALK-1930) is that CopyBinaries() recurses
into some directories and tries to copy each subpath individually. Not
only is this entirely unnecessary, but the code does it the wrong way
and, for ARM builds, creates something like
'jni/xwalk_core_library_java.jar/armeabi-v7a/libxwalkcore.so'.

Instead of just fixing one issue, rewrite the whole script in a saner,
much smaller and more Pythonic way:

* Remove a lot of unnecessary functions.
* Get rid of the "-s" option which was not being used at all.
* Stop calling sys.exit() in main() since it's supposed to return an
  exit code instead.
* Stop copying files from xwalk_core_library/ into an intermediate
  directory and just write them to the zip file directly.
