dev-lang/rust: drop preinst/postinst workaround for 1.84.{0,1}

This workaround is only required when migrating from non-slotted
Rust to slotted Rust. Since these versions have never had
a non-slotted counterpart, this step is superfluous.

Remove it now in conjunction with an unrelated revbump so that
the workaround isn't carried forward any further.
