x.py: allow a custom string appended to the version

Browse source 
This adds `rust.description` to the config as a descriptive string to be
appended to `rustc --version` output, which is also used in places like
debuginfo `DW_AT_producer`. This may be useful for supplementary build
information, like distro-specific package versions.

For example, in Fedora 33, `gcc --version` outputs:

    gcc (GCC) 10.2.1 20201016 (Red Hat 10.2.1-6)

With this change, we can add similar vendor info to `rustc --version`.
