perf trace: Fix segfault on perf trace -i perf.data

When replaying a previous record session, it'll get a segfault since it
doesn't initialize raw_syscalls enter/exit tracepoint's evsel->priv for
caching the format fields.

So fix it by properly initializing sys_enter/exit evsels that comes from
reading the perf.data file header.
