[Tizen] Apply the standalone patch based on the former
commit in crosswalk.spec [commit-id:
34ae72829837a329e3e8c9124f9a6b9f0792833e].

To complete the "Enabling Hardware Acceleration with Libva and
EGL in VDA for Tizen Mobile within chromium ".

Also, this PR will fix the two former bugs:
1. The "./libva/" not be included into ./gpu/, which will cause
compiling fails during without "share_library" type of building.

2. Change format of the former patch to make it be applied
with '$Patch' command easily.
