rust-revlog: fix lifetime problem for RevlogEntry parent entries accessors
Without this, the lifetime of the result is equated to the lifetime of the
`self` reference, preventing callers, e.g., to take a `RevlogEntry` and
return its `p1_entry()`, as it looks like returning something that does not
outlive the *reference to* the `RevlogEntry`.
