[PATCH] aisleriot: pick up the specified guile version

[Omar Polo <op omarpolo com>]

Hello,

aisleriot' meson.build has a -D flag to specify the guile version, for
example -Dguile=2.2.  The problem is that it always ends up chosing the
newer one available, even when -Dguile=X.Y was specified.

So, if i want it to build with guile2.2 while having guile3 installed
-Dguile=2.2 would still end up linking to guile3, which is unexpected.

diff below fixes it for me, tested on OpenBSD-CURRENT.

I hope it's fine to send patches here.  looking at the archive this
mailing list was empty for some time; i'm making an attempt to avoid
having to mess with gitlab :)

Cheers,

Omar Polo
