The font has no italic but inkscape slants the regular and bold styles to get them,
you can do the same in context with the slant key from \definefontfeature.

\definefontfeature[slanted][default][mode=base,slant=.25]

\definefontfamily[roboto][rm][Roboto Slab][it=features:slanted,bi=features:slanted]

\setupbodyfont[roboto]

\starttext
Regular {\it Italic} {\bf Bold} {\bi BoldItalic}
\stoptext
