[Buildroot] [PATCH] Backport valgrind patch to fix build on 4.0 host kernels

[Christian Artin]

Valgrind fails to build when the host kernel is >=4.0. This patch
backports the commit from upstream that fixes the kernel version
verification. This verification is pointless for buildroot anyway, but
it fixes the building process.

Thanks, committed with a few minor fixes:

- We already have a 0001-.. patch for valgrind, so renamed to 0002-Fix..
- Added your Signed-off-by to the patch as well.
- Reworded title so it starts with valgrind:
