trivial-builders: add meta.mainProgram to writeShellScriptBin
Derivations built with `writeShellScriptBin`
should always be runnable with `nix run`. At present,
the derivation is missing both `meta.mainProgram`
and `pname`– this means that `nix run` falls back
to inferring the bin path from `name`. This is
unreliable and depends on faulty heuristics.
For context, reference the following snippet from
`nix run --help`:
If installable evaluates to a derivation, it will try to execute the
program <out>/bin/<name>, where out is the primary output store path
of the derivation, and name is the first of the following that exists:
· The meta.mainProgram attribute of the derivation.
· The pname attribute of the derivation.
· The name part of the value of the name attribute of the derivation.
