perf report: Introduce special handling for pipe input

Adds special treatment for stdin - if the user specifies '-i -'
to perf report, the intent is that the event stream be written
to stdin rather than from a disk file.

The actual handling of the '-' filename is done by the session;
this just adds a signal handler to stop reporting, and turns off
interference by the pager.
