[x265] MSYS2/MinGW - ccache hook probably not well supported

[Mario *LigH* Rohkrämer]

The media-autobuild suite recently added experimental support for ccache 
(provided by MSYS2 as mingw-w64-x86[_64]-ccache 3.7.2-1).

The configuration step for x265 seems to fail requesting its feature set 
correctly, I even doubt it is aware of its presence at all, and its 
hooking into compiler calls might have unwanted side effects.

An example from the configuration in an MSYS2-64/MinGW32 compilation:

+----
-- cmake version 3.15.2
CMake Deprecation Warning at CMakeLists.txt:10 (cmake_policy):
   The OLD behavior for policy CMP0025 will be removed from a future version
   of CMake.

   The cmake-policies(7) manual explains that the OLD behaviors of all
   policies are deprecated and that a policy should be set to OLD only under
   specific short-term circumstances.  Projects should be ported to the NEW
   behavior and not rely on setting a policy to OLD.


CMake Deprecation Warning at CMakeLists.txt:16 (cmake_policy):
   The OLD behavior for policy CMP0054 will be removed from a future version
   of CMake.

   The cmake-policies(7) manual explains that the OLD behaviors of all
   policies are deprecated and that a policy should be set to OLD only under
   specific short-term circumstances.  Projects should be ported to the NEW
   behavior and not rely on setting a policy to OLD.
