[PATCH 1/4] perf tools: Remove repipe argument from perf_session__new()

From: Namhyung Kim
Date: Wed Jul 07 2021 - 14:05:43 EST

The repipe argument is only used by perf inject and the all others
passes 'false'. Let's remove it from the function signature and add
__perf_session__new() to be called from perf inject directly.

This is a preparation of the change the pipe input/output.
