Subject: pkgs/vim: Add rustfmt with custom default config

Since I do have a lot of projects where I use rustfmt, it gets pretty
tedious to manually run "cargo fmt". Using g:rustfmt_autosave should
make this less tedious but it might annoy me in the future, let's see.

In addition to setting rustfmt I also added a default path for rustc,
which is used whenever there is no rustc in path. This is because I
usually switch between several projects which use different Rust
versions and this way it will use the rustc version that is in PATH
during "nix develop".

For the rustfmt part I also added a small default configuration which
represents my opinion on how I think Rust code should be formatted. The
file is used whenever a project doesn't have a "rustfmt.toml" or
".rustfmt.toml".

Unfortunately, RustFmt is broken in Vim right now[1], so I'm using the
upstream project until the issue has been resolved.
