flutter: refactor and reduce derivation size

Browse Source 
Instead of copying the whole dart derivation to bin/cache/dart-sdk
directory, just symlink it.

Also, make sure that the flutter is build from dart passed as a
parameter.

Before:
/nix/store/p3avfmvd0yrjpwwml7vvqbjin5vacx2k-flutter-stable-1.22.0	2084894968

After:
/nix/store/750k4z1yj5xsw7ymmwvn7cfjjzkaygzg-flutter-stable-1.22.0	1647047080
