check: respect --no-unicode-normalization and --ignore-case-sync for --checkfile

Before this change, --no-unicode-normalization and --ignore-case-sync
were respected for rclone check but not for rclone check --checkfile,
causing them to give different results.

This change adds support for --checkfile so that the behavior is consistent.
