Be more lax when picking up prefixes for loaddefs

* lisp/emacs-lisp/loaddefs-gen.el
(loaddefs-generate--compute-prefixes): Allow tabs and spaces before
symbol name, so that "(defvar\tfoo-bar nil)" is properly picked up.
Before this change, such a definition would be wrongly picked up as
the symbol "nil".
