rust/util: use anyhow's native chaining capabilities

This simplifies conversions, making it possible to convert any error
into a QEMU util::Error with ".into()" (and therefore with "?").

The cost is having a separate constructor for when the error is a simple
string, but that is made easier by the ensure! macro. If necessary,
another macro similar to "anyhow!" can be returned, but for now there
is no need for that.

The macro is similar to anyhow::ensure but uses QEMU's variation
on anyhow::Error. It can be used to easily check a condition
and format an error message.
