[dts][PATCH V3] tests/dcf_lifecycle: add kernel check in test script

[Hongbo Li]

1.Some testcase require the kernel 4.19+ in the testplan, but test script does not check the kernel. Which will cause the lower version of kernel to fail when run cases.
2.The "--color" option of dmesg command is not supported in the OS with the lower version kernel, and the option only changes the color of the output. So delete this option to make the OS with the lower version kernel support some testcase.

v2:skip case of test_dcf_with_adq_03
v3:assigning an initial value to the variable self.kernel_version, and optimization warning log.
