perf trace: Fix summary_only option
The intent of the -s/--summary-only option is to just show a summary of
the system calls and statistics without any of the individual events.
Commit e596663ebb2 broke that by showing the interrupted lines:
perf trace -i perf.data -s
...
0.741 ( 0.000 ms): sleep/31316 fstat(fd: 4, statbuf: 0x7ffc75ceb830
) ...
0.744 ( 0.000 ms): sleep/31316 mmap(len: 100244, prot: READ, flags:
PRIVATE, fd: 4 ) ...
0.747 ( 0.000 ms): perf/31315 write(fd: 3, buf: 0x7d4bb0, count: 8
) ...
...
Fix by checking for the summary only option.
