[PATCH 1/2] ftrace: draw_funcgraph.py: Handle dots in function names

[asnast@gmail.com]

From: Alex Snast <alexsn@il.ibm.com>

ftrace function tracer can output the following line:
mmcommon-3250  [001] 969103.003748: clear_buddies.isra.59 <-dequeue_task_fair

However the regex used by draw_functrace.py would fail to match the '.'
character
