Commit 17f8e37ed5 ("Convert toolchain file to TOML syntax") switched
from the bare toolchain file to the TOML-based one for better management
of the toolchain and components used.
Commit 1cb61e6918 ("deps.sh: Update rustup or inform user of env
vars") added an explicit `rustup self update` because there were still
cases, a year later, of people not having a rustup new enough to support
the TOML-based toolchain file.
Now 2 years after that, it should be safe to drop the explicit self
update. The TOML format has widespread adoption and rustup now self
updates by default. This should allow distro-provided rustup, which
disables the self update feature, to work if it is already installed in
place of the one downloaded from https://rustup.rs.

Install a hook to run lints at pre-commit to force issues to be fixed
during development.
This introduces a 5-10 second delay when committing due to how slow
clang-format is.

Ensure rustup is up-to-date to avoid users having a version that is too
old to support the TOML format.
If rustup was just installed, tell the user to source the new env vars
to use the correct version of the toolchain.

rustup 1.23.0 (2020-11-27) introduced support for TOML syntax for the
toolchain file. Use this and specify required compoenents.
To ensure you are using a new enough rustup, run:
rustup self update
