Fix 'partial-completion' for candidates containing newlines

'partial-completion' tries to match a pattern containing wildcards
(such as `any' or `prefix') against completion candidates.
Wildcards are supposed to match any sequence of characters, but
'completion-pcm--pattern->regex' transformed the wildcards into
".*", which won't match sequences containing newlines.  Fix this to
properly match anything by using "[^z-a]*" instead.
(That's (rx (* anything)).)
* lisp/minibuffer.el (completion-pcm--pattern->regex): Fix
regex.  (Bug#72425)
