just-mrrc: support remote-execution properties

While just-mr does not use remote-execution properties, it is
still useful to have those as a separate entry in the rc file. With
rc-file delegation, this gives committed rc files an easy way to
specify the image to be used without having to set all the remaining
arguments for the various just subcommands in "just args".
