Subject: [PATCH] test_read: make it run without Docker

Apply an existing fix to `test_read`, so that it falls back to use
the current username instead of the hardcoded `libssh2` when run
outside Docker.

This allows to run algo tests with this command:
```shell
cd tests
./test_sshd.test ./test_read_algos.test
```

Closes #1139
