[RFC PATCH 5/6] rust: pin-init: allow doctests to refer to the pin-init crate

[Benno Lossin]

The next commit will name the pin-init crate from proc macros via
`::pin_init`. For this to work within tests of the pin-init crate
itself, it needs to be able to refer to itself via that name. Thus add
the required code for the name to be available.
