bug#61352: rust tarballs include precompiled amd64 binaries

[Andrius Štikonas]

Rust source tarballs ship two precombiled amd64 binaries 
vendor/vte/vim10m_{match,table} that should not be included.
I'm not sure whether they are actually used but we should still remove them.

Those binaries come from vte 0.3 crate and upstream is willing to upgrade vte 
to fix it
https://github.com/rust-lang/rust/pull/107710
So hopefully rust 1.68 will not have this problem anymore.

Note that this also affects rust-bootstrap package.
