[Buildroot] [PATCH 1/1] set minimum cmake version to 3.10

[Adam Duskett <aduskett@gmail.com>]

The CMakeLists.txt file uses the CMP0091 which is an MSVC runtime library flag
abstraction macro.

Because we are not building ninja for Microsoft, it is safe to remove this
macro and set the minimum version to 3.10.
