[bug#72553] [PATCH 2/4] gnu: rust: Fix building.

[Christopher Baines <mail@cbaines.net>]

From: Efraim Flashner <efraim@flashner.co.il>

* gnu/packages/rust.scm (rust)[arguments]: Adjust 'unpack-compiler-rt
phase to correctly copy the sources into the target directory.  Adjust
'enable-profiling phase to come after an existing phase.
[native-inputs]: Add clang-runtime-source.
