make.bat: cache the vcredist directory.

When run from make.bat the environment is setup correctly and the VCToolsRedistDir environment variable exists, on later invocations of cmake this may no longer be the case and a warning was emitted about the missing runtime. we can't rely on InstallRequiredSystemLibraries.cmake here since it uses the compiler version to figure out the correct location and it doesn't know how to deal with clang.
