bug#58067: 29.0.50; Miscomputation of percentage width in vtable--compute-width

[Pierre Lairez <pierre@lairez.fr>]

(eq (vtable--compute-width nil "100%") (window-width nil t))
shoud be true.

In the file lisp/emacs-lisp/vtable.el, in the function
vtable--compute-width, do not handle percentage argument, like "50%",
correctly. A division by 100 is missing.
