cmake: Fix variable type usage.

Silences a noisy warning with a couple of variations. It looks like
this:

CMake Warning (dev) at /Users/tomfinegan/_werk/aom/build/cmake/util.cmake:146 (set):
  implicitly converting 'NUMBER' to 'STRING' type.
Call Stack (most recent call first):
  /Users/tomfinegan/_werk/aom/build/cmake/aom_config_defaults.cmake:<line num> (set_aom_config_var)
This warning is for project developers.  Use -Wno-dev to suppress it.
