path too long error fix

[danielschickmunit]

Fixes #948

changes the names for the temporary file_paths from
labgrid-ssh-tmp- to lg-ssh-
and
labgrid-connection- to lg-con-

in order to be compatible with MacOS and its longer tempdir-path

Is this the only change needed for MacOS? So far, we only support Linux and I wouldn't make want to make MacOS a supported platform as that could limit us in the future.

as far as i can tell it's the only thing that has to change, but i can't tell if all features of the client will work, I'm only using the labgrid-client on MacOS and the rest will run on linux machines

for the sake of completeness
I also had to install the labgrid python package via python3 -m pip install .

the features that i'm using for the client on MacOS is ssh to the exporter and ser2net connection to the dut

it's understandable that only support for linux is desired. For the rest I use the docker-images that I build using the dockerfile

I mostly use MacOS natively to be able to debug labgrid via vscode but I could also attach the debugger to the container

FWIW this also happens on Linux, so its not macOS exclusive. Can you fix the DCO by adding a signed off by?
