Upgrading lang/rust to 1.64.0

[Havard Eidnes <he%NetBSD.org@localhost>]

Hi,

it's time again to upgrade rust in main pkgsrc.  Upstream is
already at 1.65.0 which I have waiting in the wings.

The testing I've done is sumarized in the table below; I've not
really hit any notable problems, and managed to build at least
and run one firefox.

Comments?

Regards,
