[Trusty SRU] Provide compat macro for skb_get_hash

[Stefan Bader]

I think this should do the trick. Not tested, so given it looks so
simple, maybe it is wrong.

Subject: [PATCH] UBUNTU: SAUCE: Add compat macro for skb_get_hash

Commit df4530d690a14dd net: Change skb_get_rxhash to skb_get_hash
changed a function that is part of the 3.13 kernel API to pull in
some newer driver code.
In order for external modules (which check the LINUX_VERSION_CODE
to find out which API functions to use) to still compile correctly,
add a compat definition for the old name.
