transport-helper: ask the helper to set the same options for import as for fetch

A remote helper is currently only told about the 'check-connectivity',
'cloning', and 'update-shallow' options when it supports the 'fetch'
command, but not when it supports 'import' instead.

This is especially important for the 'cloning' option, because it
means a remote helper that only supports 'import' can't distinguish
between a clone and a pull besides doing some assumptions from the
git directory state.
