Only define gethookproxy, isinitpath on Session

This fixes an issue where pylint complains about missing implementations
of abstract methods in subclasses of `File` which only override
`collect()` (as they should).

It is also cleaner and makes sense, these methods really don't need to
be overridden.

The previous methods defined directly on `FSCollector` and `Package` are
deprecated, to be removed in pytest 7.

See commits e2934c3f8c03c83469f4c6670c207773a6e02df4 and
f10ab021e21a44e2f0fa2be66660c4a6d4b7a61a for reference.
