[PATCH v1] perf trace: Disable syscall augmentation with record

[Ian Rogers <irogers@google.com>]

Syscall augmentation is causing samples not to be written to the
perf.data file with "perf trace record". Disabling augmentation is
sub-optimal, but it beats having a totally broken perf trace record.
