Fix typo in big object fix for Windows.

Fix typo in big object fix for Windows.

There is no such thing as VCCompilerTool so gyp did nothing but warn
a thousand times. VCCLCompilerTool on the other hand will actually
do something.

Hah - that's funny. That explains the 5,644 warnings when using the msvs-ninja
generator:

    Warning: unrecognized tool VCCompilerTool while converting to MSBuild.

This is the second recent instance of the msvs-ninja generator finding bugs
(https://codereview.chromium.org/1208703002) that are not otherwise noticed.
We'll have to keep that in mind.

It will also make running gyp_chromium from the prompt 10 seconds faster!
Because cmd.exe is crazy slow (trying to be compatible with MS-DOS speeds?) and
printing 5k warnings take a little while.
