rust: pin-init: allow the crate to refer to itself as `pin-init` in doc tests
The `syn` approach requires use of `::pin_init::...` instead of the
`$crate::...` construct available to declarative macros. To be able to
use the `pin_init` crate from itself (which includes doc tests), we have
to declare it as such.
