fix: run tor daemon with distinct user

[theborakompanioni]

Closes #60.

Before this PR the tor daemon ran as user root.
After this PR a distinct tor user is created and used to start the tor daemon.

Image of this branch is published and can be tested by pulling
docker pull ghcr.io/joinmarket-webui/jam-dev-standalone:tor-user

I tried to use the tor-user image by changing one line in the Dockerfile:

diff --git a/docker/regtest/dockerfile-deps/joinmarket/webui-standalone/Dockerfile b/docker/regtest/dockerfile-deps/joinmarket/webui-standalone/Dockerfile
index 6a8b677..9e8da0f 100644
--- a/docker/regtest/dockerfile-deps/joinmarket/webui-standalone/Dockerfile
+++ b/docker/regtest/dockerfile-deps/joinmarket/webui-standalone/Dockerfile

-FROM ghcr.io/joinmarket-webui/joinmarket-webui-dev-standalone:master
+FROM ghcr.io/joinmarket-webui/joinmarket-webui-dev-standalone:tor-user

Unfortunately, it failed with the following error on npm run regtest:rebuild:

Sending build context to Docker daemon  18.94kB
Step 1/3 : FROM ghcr.io/joinmarket-webui/joinmarket-webui-dev-standalone:tor-user
manifest unknown
ERROR: Service 'joinmarket2' failed to build : Build failed

I tried again after running a regtest:clear just to make sure. Same result.

The image is jam-dev-standalone:tor-user not joinmarket-webui-dev-standalone:tor-user 😉

Ah, damn 🤦 - give me another minute.

All good, problem was on my side, obviously.
