Zack Middleton 5ede35d8dd Fix building QVMs on Linux with Windows line endings
On non-Windows, compiling QVM tools failed if dagcheck.md had CRLF line
endings and compiling QVMs failed if game source had CRLF line endings.

Also made Windows open the files as binary (no automatic CRLF to LF) so
it behaves the same as on non-Windows.
