netifaces recipe include path

[brussee]

Fixes #802 by setting include path.

Unfortunately this does not fix the problem entirely:

import netifaces
exceptions.ImportError: dlopen failed: cannot locate symbol "PyExc_OSError" referenced by "/data/data/org.tribler.android/files/lib/python2.7/site-packages/netifaces.so"...

This will be fixed when/if merged PR #793. If you take a look at PR#783 you will see that that fix depends on it...so i think that this is not necessary if PR #793 is finally merged. What do you think @brussee?

PD: This is a hack only for this recipe...the PR #793 fixes the problem for several recipes.

Then #783 should not have been merged if it breaks the recipe until #793 is merged.

I reverted to the old recipe, because I am under high pressure to deliver my app.

@opacam I whish you success with the 2.7.11 endeavor!

See #841.
