erlang-27: add odbc subpackage

[sando38]

Pre-review Checklist

This adds the erlang-odbc library to the build outcomes, which was previously not included. I bundled it as a subpackage to not increase the erlang base package.

For a project I need the erlang-odbc library, currently I am recompiling erlang including the two missing build dependencies. This subpackage would make it irrelevant :)

P.S. This may be also interesting to "backport" to erlang-25 and erlang-26 packages.

For new version streams

• The upstream project actually supports multiple concurrent versions.
• Any subpackages include the version string in their package name (e.g. name: ${{package.name}}-compat)
• The package (and subpackages) provides: logical unversioned forms of the package (e.g. nodejs, nodejs-lts)
