system - split the lsb_release parameters for compatibility with armbian - fixes #2897

Armbian uses a minimal bash script replacement for lsb_release that uses basic parameter
parsing and requires the arguments to be split rather than using -sidrc

Note that Armbian isn't officially supported or tested
