Increase NOFILE limit for tox-bootstrapd

tox-bootstrapd can use around 600 TCP sockets during TCP server's normal
functioning. Many systems default to having a soft limit of 1024 open file
descriptors, which we are close to reaching, so it was suggested we bump that
limit to a higher number. iphy suggested increasing it to 32768.
