luv: Add timestamp to luv-parser-fwts

Modify luv-parser-fwts to get a timestamp on
frontline of each unittest when fwts executed

Changes will meet the schema 1.1 version updated
in the luv-test-parser file by Matt Fleming and now the
format looks like this
"1.1 timestamp fwts unittest RESULT 1 0 0 0"

Patch provides the clear understanding of how much
time did each of the unittests take to run
