loader: fix ECS after new-ipc rewrite ...

The call to serviceCreate(...) tries to query pointer buffer size, but
since we haven't had a chance to return the server side of the session
yet, this deadlocks. Instead, we defer creating the session and
mounting the filesystem until the first time the ECS object is
used. If mounting the filesystem fails, the ECS is silently discarded.

pm: fix process exit on < 5.0.0 (closes #748) (thanks @misson20000)
