Revert "upload-build.sh: Create upload directory before using rsync"

This reverts commit d6d0c3c644.

Revert as it's not useful because the host doesn't accept ssh
connections. In this case, ssh will return exit code 0 but no work will
be done. It can be easily tested with "ssh sysmocom-downloads ls /"
which outputs nothing. Trying to acces a console through ssh errors
directly with a message.
