build: restrict the use of --with-slang to together with --enable-tiny

Slang contains bugs that get triggered when resizing the terminal,
or rather: when its existing data structures get reinitialized.
Avoid those bugs by forcing the exclusion of the resizing code
when nano is configured with --with-slang.

(The only reason for not entirely eliminating the support for Slang
is to allow Debian to build a tiny nano against Slang for on their
install image.)

This avoids https://savannah.gnu.org/bugs/?57520,
and avoids https://savannah.gnu.org/bugs/?57518,
and dodges https://savannah.gnu.org/bugs/?57513,
and dodges https://savannah.gnu.org/bugs/?57507.
