cargo2ebuild: Handle version parse errors and do not replace existing.
This adds:
* error handling for version parse errors, so the script can
still be used (with user cleanup required).
* a '-x' command line flag that can be used to overwrite existing
ebuilds. The new default behavior is to leave existing ebuilds.
BUG=None
TEST=manual testing.
