cpumf/lshwc: Add command line flag for run time

Browse Source 
Add a command line flag to specify run time of lshwc command in
terms of days, hours, minutes and seconds. The command line flag
is named -t and has a number as argument followed by one of the
letters 's' for seconds (default), 'm' for minutes, 'h' for hours
and 'd' for days. Default is seconds when no trailing letter is
detected.
