perf evlist: Add perf_evlist__to_front()
Add a function to move a selected event to the
front of the list.
This is needed because it is not possible
to use the PERF_EVENT_IOC_SET_OUTPUT IOCTL
from an Instruction Tracing event to a
non-Instruction Tracing event. Thus the
Instruction Tracing event must come first.
