Another dumb mistake when using bourne shell:
```
/var/lib/dpkg/info/nimbus-beacon-node.postinst: 23: source: not found
```

The `postinst` wrapper script into which these scripts are embedded as
`after_upgrade` and `after_install` functions are executed using Bourne
shell(`sh`), so we cannot use the Bash specific `[[ ]]` test or it fails:
```
/var/lib/dpkg/info/nimbus-beacon-node.postinst: 22: [[: not found
```

The `/etc/os-release` file exists in most distributions and can be
easily read in Bash by sourcing it:
```
> docker run --rm -it debian:bullseye
root@2f5d6e038738:/# grep '^ID=' /etc/os-release
ID=debian
```
```
> docker run --rm -it ubuntu:22.04
root@316b572b6e4d:/# grep '^ID=' /etc/os-release
ID=ubuntu
```
The dependency on `lsb-release` tool
is unnecessary, and pulls in additional big dependencies like `python3`:
```
# apt show lsb-release | grep Depends
Depends: python3:any, distro-info-data
```
Which if used in a Docker container would make it unnecessarily big.

Otherwise installation in Docker containers fails with:
```

Adding new user `nimbus' (UID 101) with group `nimbus' ...
Not creating home directory `/home/nimbus'.

* packaging updates
* one package per binary (nimbus_beacon_node, nimbus_validator_client)
* use `-` in package name (`_` is separating the version)
* don't include (un)installation scripts in package
* default metrics port 8108 for vc
* fix several upgrade/install errors in scripts
* add JWT option to service files
* don't attempt to remove user on purge
