Nick Craig-Wood ef7bfd3f03 fs: Make prefix free backend config read prefix free env var also
Before this change you could only configure the local backend flags
which don't have the local prefix (eg `--copy-links`) with
`RCLONE_LOCAL_COPY_LINKS`.

This change makes `RCLONE_COPY_LINKS` valid too which is much more
logical for the users.

Fixes #3534
