Ravi Bangoria 739cf30551 perf trace: Add usage of --no-syscalls in man page
perf trace supports --no-syscalls option but it's not listed in the man
page. (Though, I see an example using --no-syscalls in EXAMPLES
section.)

Committer note:

The --no-syscalls option tells 'perf trace' not to automagically ask for
raw_syscalls:sys_{enter,exit} to then format it in a strace like way.

This become more used as 'perf trace' got support for arbitrary events,
such as tracepoints, so more and more we use:

  # perf trace --no-syscalls -e nmi:*
     0.000 nmi:nmi_handler:perf_event_nmi_handler() delta_ns: 36649 handled: 1)
     0.019 nmi:nmi_handler:nmi_cpu_backtrace_handler() delta_ns: 2907 handled: 0)
     0.676 nmi:nmi_handler:perf_event_nmi_handler() delta_ns: 9401 handled: 1)
     0.680 nmi:nmi_handler:nmi_cpu_backtrace_handler() delta_ns: 288 handled: 0)
     0.701 nmi:nmi_handler:perf_event_nmi_handler() delta_ns: 4977 handled: 1)
     0.703 nmi:nmi_handler:nmi_cpu_backtrace_handler() delta_ns: 67 handled: 0)
     0.736 nmi:nmi_handler:perf_event_nmi_handler() delta_ns: 8549 handled: 1)
