basic/namespace-util: fix double logging after fork failure

[   10.056930] (journald)[104]: Failed to fork off '(sd-mkuserns)': Invalid argument
[   10.063727] systemd[1]: systemd-modules-load.service: About to execute: /usr/lib/systemd/systemd-modules-load
[   10.071148] (journald)[104]: Failed to fork process (sd-mkuserns): Invalid argument

safe_fork_full() already logs at debug level, so the caller shouldn't.
