treewide: Rename android sdkVer and ndkVer

`sdkVer` conflicts with the old `sdkVer`(now `darwinSdkVersion` but that still uses `sdkVer` if set) used by darwin

This shouldn't be an issue but due to `pkgs/development/interpreters/python/cpython/default.nix`
running `lib.filterAttrs (n: v: ! lib.isDerivation v && n != "passthruFun")` on it's inputs (2 of them are darwin only)
the `throw "Unsupported sdk...` in `pkgs/top-level/darwin-packages.nix` will be triggered.

After this change `pkgsCross.armv7a-android-prebuilt.python3.pythonOnBuildForHost` won't fail with
`error: Unsupported sdk: 33`

Issue was bisected to 3cb23cec23
