gst-env: Fix creation of gdb-autoload dirs on Windows

`bdir[1:]` is supposed to convert `/path/to/bdir` to `path/to/bdir`
which is only correct on UNIX. On Windows it will convert
`C:\path\to\bdir` to `:\path\to\bdir` which is totally wrong.

Use pathlib instead, which makes it trivial to do the conversion using
`joinpath(*bdir.parts)`
