Add linux3 build support to chromium (base repository)

Add support for Linux kernels >=3.0-rc1 in Python related build files by: 
 - replacing occurences of sys.platform == 'linux2' with 
    sys.platform.startswith('linux') 
 - congregating occurences of sys.platform in ('linux[X]', 'linuxY', ...) 
    to sys.platform.startswith('linux') 
  - adding the key 'linux3' to all relevant lookup dicts 

BUG=85845
TEST=Try building chromium on Linux >=3.0-r1

Hi Paweł,

so, this is the new patch for chromium base repository, without any third-party
stuff. Should I close 7148011 now, so things don't get mixed up even more?

Can you wait until I've landed http://codereview.chromium.org/7181002/ then sync
to tip of tree and re-upload the patch?  It should remove all the .grd changes
and the change to tools/grit/grit/node/base.py.  Thanks!

Yes, of course. That sounds reasonable.

LGTM - now we shouldn't need any OWNERS checks and there are no grit changes,
and I've verified that you've signed the CLA, so I'm going to click the commit
