wolf: fix info.zip pack never actually installing (broke content matching for every core)

Confirmed live: RetroArch's file browser and directory-scan importer both
failed to recognize SNES ROMs (.sfc) even though the ROM files and the
snes9x core .so were both genuinely present and correctly mounted — the
core's own .info file (which declares supported_extensions) was never
actually installed, because the "already present, skip" check for the
info.zip pack was "is $CORES_DIR non-empty", and $CORES_DIR is always
non-empty by the time that check runs (the core .so files fill it first,
earlier in the same `cores all` run). So the info-pack fetch silently
no-op'd on every single install, fresh or not — not specific to this
laptop.

Give "info" its own real check: does $CORES_DIR actually contain any
*.info files, not just anything at all.
