perf inject: Fix repipe usage
Since commit 14d3d54052539a1e ("perf session: Try to read pipe data from file") 'perf inject' has started printing "PERFILE2h" when not processing pipes. The commit exposed perf to the possiblity that the input is not a pipe but the 'repipe' parameter gets used. That causes the printing because perf inject sets 'repipe' to true always. The 'repipe' parameter of perf_session__new() is used by 2 functions: - perf_file_header__read_pipe() - trace_report() In both cases, the functions copy data to STDOUT_FILENO when 'repipe' is true. Fix by setting 'repipe' to true only if the output is a pipe.
