lib: Make UNIX socket buffer size configurable0.11.3

This makes the buffer size used by the UNIX sockets configurable. In
case of a lot of IPCPs in the system it might become too small with
the default value, resulting in irm command failures. The user can now
easily configure it with an adequate value.
