[dts][PATCH V1] tests/dcf_lifecycle: optimize script

[Hongbo Li]

The "--color" option of dmesg command is not supported in the OS with the lower version kernel, and the option only affects the color of the output.
So delete this option to make the OS with the lower version kernel support some testcase.
