Linux: change gyp and add a shim header to build with system speex.

This will be useful for Linux distributions shipping Chromium.
The default setting is still to build with the bundled speex library.

More changes will be required (in src). This is the part in deps.

can you also update the files which currently include this header file to point
to the new path? I remember src/chrome/browser/speech/speech_recognizer.cc is
one of them, not sure if there are more.

Yes, that's definitely my plan. Note however that this is change in deps/ and
the other files are in src/ . We'll need to land this change, roll DEPS for
speex, and finally update src (yes, there's just one file you've mentioned to
update).

I used that sequence for icu (another library that sits in deps), and it worked
fine without breaking the tree at any point.
