[dts] [PATCH] Change output folder path and optimize virt dut log

[Yong Liu <yong.liu@intel.com>]

From: Marvin Liu <yong.liu@intel.com>

Previously all output files will be saved in output folder dts.log and
"suite.log". The log information will be appended in the log file. The log
file will be huge and difficult to trace after running dts several times.

Now log files will be saved in output/folder_name_by_time.
