Binman requires various tools to actually work, such as 'lz4' to compress data and 'futility' to sign Chrome OS firmware. At present these are handled in an ad-hoc manner and there is no easy way to find out what tools are needd to build an image, nor where to obtain them.
Add an implementation of 'bintool', a base class which implements this functionality. When a bintool is required, it can be requested from this module, then executed. When the tool is missing, it can provide a way to obtain it.
Note that this uses Command directly, not the tools.Run() function. This allows proper handling of missing tools and avoids needing to catch and re-raise exceptions.
