DTLSSocket installation

[Fleaurent]

I get the same error trying to install DTLSSocket, as a dependency for aiocoap[all] complaining about
"trying to run sh failed, please make sure sh is install" on all my systems:
i.e. windows, WSL and docker ubuntu container using

RUN apt-get update && apt-get install -y
python3
python3-pip
build-essential
automake
autoconf
libtool

$ pip install DTLSSocket
