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 e596663e 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.
