Add small elabinelab hack for Mike, allowing you to set tarfiles for
inner boss and ops:

	namespace eval TBCOMPAT {
	    set elabinelab_tarfiles("boss") "/usr/site /foo/silly.tar.gz"
	}

Ditto for "ops". You can specify multiple tarfiles of course in the
string, just as tb-set-node-tarfiles allows.
