[bug#54439] [PATCH core-updates 1/2] gnu: rust: decouple rust-1.57 and "rust"

[Jim Newsome]

From: Jim Newsome <jnewsome@torproject.org>

* gnu/packages/rust.scm (rust-1.57, rust): decouple the definition of
rust-1.57, which happens to be the current latest, from the definition
of rust, which is always the latest. The latter re-enables tests and
extra components, which should always be done only on the final public
rust package, not specifically rust-1.57.
