36-diskstatus - Journalctl now default search location for smartctl

This release of 36-diskstatus should allow support for all systemd based systems, not just Ubuntu. Tested on Manjaro (Arch) as well.

36-diskstatus changes:

• NEW: Defaults to journalctl. Optional specify specific log files for syslog, etc.
• NEW: Define number of search days for journalctl for smartd entries
• NEW: Now removes text "_with_Heatsink" for smaller device names
• FIX: Filters out weird duplicate device names ending in "_1"
• FIX: Renders on systems with only NVMe devices (where no smartctl log entries)
• FIX: hddtemp support removed - Project was deprecated long ago
