Mono: Runtime main args and assembly search fixes

- Setup runtime main args during initialization. This must be done manually by embedders who do not call mono_runtime_run_main. Fixes NullReferenceException in System.Environment.
- Continue to search the assembly in the rest of the search locations if loading it from one of them failed.
