fix: foundry root imports

[antico5]

This change fixes imports on foundry projects where they use paths relative to project root (i.e. import 'src/MyContract.sol'). It changes both the import resolution and the solc input as well. For foundry projects, solcInput.sources keys are not absolute paths, but paths relative to project root. (i.e. '/home/user/myProject/src/Contract.sol' => 'src/Contract.sol'). This is the only way I found for json-interfaced solc to deal with circular dependencies that use root-relative imports.
