Fix GN freeze on generating Visual Studio projects

There's an infinite loop while searching for parent directory. It happens
when drive letter case is mixed in absolute paths on Windows (/C:/foo and
/c:/foo). It's easily reproducible on MSYS terminals when system-absolute
paths are used for some targets and source root-absolute (//foo/bar) paths
are used for other targets.
