build.js: fix build script

vscode-html-languageserver's tsconfig changed.
 It extends `../../shared.tsconfig.json` that is
`https://github.com/microsoft/vscode/blob/master/extensions/shared.tsconfig.json` now.
So I copy and use shared.tsconfig.json. I don't want to keep up with changes in shared.tsconfig.json,
but I couldn't think of any other easy way.
The submodule directory has also been changed to match the relative path of extends in tsconfig.json.
