Bug 40190: Update toolchain for Fenix 85

We pick up the latest (currently) Rust stable version, 1.48.0.

miri fails to compile (even though the build succeeds) which is
okay-ish.

See:

rust-lang/rust#79582 and
rust-lang/rust#74709

for more details.

It's not clear why exactly we need to specify the host as a target now,
too. But I guess previously things just worked by chance. The correct
thing to do is to specify `x86_64-unknown-linux` as target, too, given
that we are targetting it, e.g. with `cbindgen`.

Note: we could think about specifying `--host` here too, but it seems we
can avoid that extra configure argument, see:

rust-lang/rust#76990.
