revise flags for vipsthumbnail

The --rotate flag no longer did anything, so add a new --no-rotate flag
connected to the new no-rotate property. --rotate is still there, but
hidden and does nothing.

-o was much easier to remember than -f, so flip back to -o. -f still
works, but is a hidden synonym.

--iprofile, --eprofile were hard to remember. Add --import-profile and
--export-profile synonyms. iprofile / eprofile are still there and still
work, but are hidden.
