Workaround for wildcard output selector bug in solc <= 0.5.8

Related to https://github.com/ethereum/solidity/issues/14214.

In https://github.com/ethereum/solidity/pull/6606 (released in 0.5.9) we fixed a bug that broke the `*` at source level. Since solc-js acts as a compatibility layer for older binaries, we should include a workaround for that bug here.

We can avoid triggering the bug by modifying the input JSON to either use `*` at contract level as well or by listing all contract explicitly.

### Repro
```json
{
"language": "Solidity",
"sources": {
"C.sol": {
"content": "pragma solidity *; contract C {}"
}
},
"settings": {
"outputSelection": {"*": {"C": ["evm.bytecode"]}}
}
}
```
```json
{
"contracts": {
"C.sol": {
"C": {
"evm": {
"bytecode": {
"linkReferences": {},
"object": "",
"opcodes": "",
"sourceMap": ""
}
}
}
}
},
"sources": {
"C.sol": {
"id": 0
}
}
}
```

Start by reproducing the provided standard JSON input and output with solc-js and a Solidity compiler binary at or below 0.5.8. Trace the input handling for outputSelection wildcards; done means the compatibility workaround avoids the old compiler bug while preserving the expected compiled output.
