Changes: * Fix OpenBSD cpu.sh output to match others * Fix OpenBSD df.sh output (no need for %% here) * Do not use sudo or doas when running as root * Use #!/usr/bin/env bash to support OpenBSD in run_nix_ta_commands * Fix rsyslog example to trim whitespace in run_nix_ta_commands * Add /usr/local/sbin:/usr/local/bin to PATH in run_nix_ta_commands * Fix getting hour and minute for OpenBSD in run_nix_ta_commands "08" shows up to printf as octal * Support difference in OpenBSD logger command: Requires modifying /etc/syslog.conf and setting facility in /etc/nix_ta.conf
