[spp] [PATCH 22/29] bin: remove sock files created by docker

[Yasufumi Ogawa <yasufum.o@gmail.com>]

If docker does mount a sock file without created before from DPDK while
launching a container, docker create an empty directory which name is
the same as the sock file.

SPP startup script removes existing sock files before launching SPP
processes, but does not directories. This update is to enable to remove
directory.
