The attached patch adds an 'options' parameter to
'mount-root-file-system' and makes 'boot-system' use it with the
content of the 'options' field of the <file-system> object for "/".

It's not exactly the solution you described (adding a keyword argument
to 'boot-system'), but I think it should work. What do you think?

I tried it with my btrfs root file system, and it is correctly mounted
with the options declared in my '/etc/config.scm' file.
