[Pkg-rust-maintainers] Bug#1095489: please upgrade dirs/directories to v6

Since the new versions of both dirs and directories depend on the
new version of dirs-sys I belive they should be handled together.

I've worked through the reverse dependencies, and intend to upload
the new versions of dirs/dirs-sys/directories to unstable once
rustc 1.91 enters testing.
