Subject: allow {white,black}listing thumbnail cache dirs (#461)

this adds the cli flags --cache-{allow,deny} along with
corresponding config.h vars which allows the user to control
which directories will have thumbnail cache written.

this is a more general version of the `cache-whitelist` patch
that existed in the nsxiv-extra repo:
https://codeberg.org/nsxiv/nsxiv-extra/src/commit/21cb27cee7/patches/cache-whitelist

Closes: https://codeberg.org/nsxiv/nsxiv/issues/454
