Downgrade `hashbrown` to meet MSRV

`hashbrown` depends on `ahash` which depends on `once_cell`. Sadly,
in https://github.com/matklad/once_cell/issues/201 the `once_cell`
maintainer decided they didn't want to do the work of having an
MSRV policy for `once_cell`, making `ahash`, and thus `hashbrown`
require the latest compiler. I've reached out to `ahash` to suggest
they drop the dependency (as they could trivially work around not
having it), but until then we simply downgrade `hashbrown`.

`rust-bitcoin` also requires an older `hashbrown` so we're actually
reducing our total `no-std` code here anyway.
