unload-feature: Correct doc string to match info manual and reality

'unload-feature' doesn't try to "undo any additions the library has
made" to hooks, it tries to remove functions defined by the library
from hooks, no matter how they got there.

* lisp/loadhist.el (unload-feature): Correct the doc string.
* doc/lispref/loading.texi (Unloading): Clarify, fix typo.
