[Buildroot] [git commit] package/grpc: remove BUILD_CSHARP_EXT option

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=e513d6a5fdf6b87eff10f759535ccc7abcef7a73
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

the CSharp Extension was removed in grcp 1.47.0 [0] and the option in
the CMakeLists was dropped in 1.58.0 [1], which means that it is no
longer relevant since Buildroot commit
91d1207de0b3cda9b9722f7ca09131cde7c14bd9, which bumped grpc from
1.51.1 to 1.66.1.

So remove this option for host-grpc as well.

Fixes:
  CMake Warning:
    Manually-specified variables were not used by the project:

      gRPC_BUILD_CSHARP_EXT
