treewide: curl: exit with error status on HTTP errors
This makes scripts fail early on request errors.
Previously, curl exited with status 0 when enountering HTTP error status
codes.
`-fsS` equals `--fail --silent --show-error`.

fetch-release: export GNUPGHOME
This approach is less error-prone.
It is also used by our fetcher scripts.

fetch-release: make GPG key searchable
The non-spaced version gives no matches in major search engines.
This is useful for auditing this script.

fetch-release: write error messages to stderr
Previously, when used to update `nix-bitcoin-release`, the error
wasn't displayed but instead written to `nix-bitcoin-release`.

Also, show curl error messages.

improve examples/shell.nix
The user's local node configuration directory usually contains a copy of
examples/shell.nix.

1. Move the shell implementation from shell.nix to nix-bitcoin/helper/makeShell.nix
   Because the shell is no longer defined locally in the user's config
   directory, we can now ship new shell features via nix-bitcoin updates.

2. Simplify examples/nix-bitcoin-release.nix
   nix-bitcoin-release.nix, as generated via `fetch-release`, now
   contains a simple fetchTarball statement which can be directly imported.
   This allows us to get rid of the extra `nix-bitcoin-unpacked` derivation
   which adds a dependency on the user's local nixpkgs.

   To keep `fetch-release` as simple as possible for easy auditing, we just
   fetch and verify a `nar-hash.txt` file that is now uploaded
   via `push-release.sh`.

A migration guide for updating the user's local `shell.nix` is
automatically printed when the user starts a new shell after updating
nix-bitcoin.
This is achieved by throwing an error in `generate-secrets`, which is called
on shell startup.

This commit is required to deploy the new extensible `generate-secrets`
mechanism introduced in the next commit.

fetch-release: minor improvements
This script is potentially fetched from an untrusted source and should
be in good shape to be easily auditable.

- Create just one TMPDIR
- Improve comments
- Use `cut` to extract sha256
- Use camelCase var names like in other scripts

Add fetch-release script
This allows getting the hash of the latest (or some other) release
using github releases and gpg verification.
