winbindd_cache: recognize and allow longer UA keys
UA keys consist of a potientally large number of concatenated SID strings which
can grow much larger than 1024 bytes in complex environments. We catch those keys
and allow them exclusivly to be larger.
(This used to be commit fcd35232e111f9b046ae35d939d08c29d0d43438)
