gnu: rust: Update rust to 1.24.1.
* gnu/packages/rust.scm (rust-bootstrap): Freeze bootstrap version to 1.22.1.
Reorganize bootstrap binaries to match new "rust" package structure with two

related dependencies.  Install "cargo" as separate "rust" output.  Remove
substitutes for parts that were fixed in "rustc" source code.  Install
documentation to separate "doc" output.  Update configuration according to
changes in "rustc" source code.  Replace all "system*" by "invoke".
(rust): Create package for 1.24.1 rust release based on rust-1.23 release.
* guix/build-system/cargo.scm (default-rust): Replace "default-cargo" and
"default-rustc" functions with "default-rust" function.

ui: 'load*' no longer fails on Guile 2.2.3 upon EACCES or similar.
Previously, if ~/.cache was not write-accessible, 'guix' would exit with
code 1 without printing any message.  That was because the 'make-stack'
call would fail since the exception (a 'system-error) came from
'compile-file', which was called at a point where TAG wasn't installed
yet.  Secondly, to mimick auto-compilation behavior, we just swallow
'system-error raised by 'compile-file'.

Reported by Clément Lassieur.
