dev-lang/rust: revbump 1.47.0, a lot of fixes

we now completely switch all components for eselect-rust.
it now includes: doc, man, lib, rustlib.

previously there was no guarantee user gets those components
from version eselected system-wide.
now all the paths are handled.
change src_compile target to 'dist'
because of changes to x.py
https://blog.rust-lang.org/inside-rust/2020/08/30/changes-to-x-py-defaults.html
minor cleanup.

Package-Manager: Portage-3.0.8, Repoman-3.0.1
