Commit 7d6a15e63c95 ("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 cf7fc2c540d5 ("scripts: 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.
