Try this:
\def\CurrentUser{\cldcontext{os.resultof"whoami"}}
\def\Markname{Compiled \date by \detokenize\expandafter{\CurrentUser} \LUATEX
+\ConTeXt\ \contextversion.}
\setuplayout[location=middle,marking=on]
\definelayer[cropmark][state=repeat,width=\paperwidth,height=\paperheight]
\setupbackgrounds[page][background=cropmark]
\setlayer[cropmark][preset=lefttop,x=3cm,y=1.5\lineheight]{\Markname}
\starttext
Foo
\stoptext
