Add configure probe for rl_completion_suppress_quote.

Browse Source 
I had supposed that all versions of Readline that have filename
quoting hooks also have the rl_completion_suppress_quote variable.
But it seems OpenBSD managed to find a version someplace that does
not, so we'll have to expend a separate configure probe for that.

(Light testing suggests that this version also lacks the bugs that
make it necessary to frob that variable.  Hooray!)

Per buildfarm.
