binder: don't unlock procs while scanning contexts
Releasing the procs lock while freezing a binder context allows for
other processes to modify the process list while the scan is still
ongoing.
Don't release the process locks during the scan operatoin, but store
matching processes in a dynamic array and process them at a later phase.
