cmake: Upgrade to v2.8.10.2 from oe-core

:Release Notes:
webOS has been using v2.8.7 so as to match what's provided by Ubuntu
12.04 (the supported version for standalone desktop development). Drop
it to use the slightly newer version provided by upstream OE.

:Detailed Notes:
The newer version has a few improvements in Qt support, but the
significant improvement is in even newer versions (from oe-core/dora or
oe-core/master) in combination with the newer meta-qt5 layer.

:Testing Performed:
Only build tested.

:QA Notes:
No change in the image.

:Issues Addressed:
[ANG-329]  Ongoing metadata improvement/cleanup work
[BHV-1392] Upgrade cmake to version from oe-core
[BHV-1393] CCC: cmake-native=v2.8.10.2 (version from oe-core)
