[PATCH] t9001: PATH must not use Windows-style paths

On Windows, $(pwd) returns a drive-letter style path C:/foo, while $PWD
contains a POSIX style /c/foo path. When we want to interpolate the
current directory in the PATH variable, we must not use the C:/foo style,
because the meaning of the colon is ambiguous. Use the POSIX style.
