[PATCH 21/26] rv/rvgen: remove unused sys import from dot2c

[Wander Lairson Costa]

The sys module was imported in the dot2c frontend script but never
used. This import was likely left over from earlier development or
copied from a template that required sys for exit handling.

Remove the unused import to clean up the code and satisfy linters
that flag unused imports as errors.
