[PATCH] Fix cache aging cleanup of threads

[Rob Herring <robh@kernel.org>]

The cache aging for threads was not running resulting in failures to
fetch new messages in threads. Fix the empty cache check which should
be for no '.msgs' directories.

Fixes: 4950093c0c3e ("Don't use mboxo for anything")
