Change default path of built executable from build/app to build/release/bin/cquery (installed to $PREFIX/bin/cquery)

This is incompatible, please change your editor configuration:

* LanguageClient-neovim: g:LanguageClient_serverCommands
* Emacs cquery.el: cquery-executable
* VSCode: cquery.launch.workingDirectory cquery.launch.command
