scripts/pybootchart: Allow minimum task length to be configured from the commandline
Rather than hardcode the value of "8", allow the minimum task length to be configured from the commandline using the -m option. "-m 0" means all tasks will be graphed. (From OE-Core rev: 30001153d3ce7dadf8f1ec79e634a638a9994518) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
