perf record: Fix use of sample_id_all userspace with !sample_id_all kernels

Check if parse_single_tracepoint_event has already asked for PERF_SAMPLE_TIME.

This is kludgy but short term fix for problems introduced by eac23d1c that
broke 'perf script' by having different sample_types when using multiple
tracepoint events when we use a perf binary that tries to use sample_id_all on
an older kernel.

We need to move counter creation to perf_session, support different
sample_types, etc.

Ongoing work on the perf test infrastructure needs this so that we can create
counters to monitor threads generating specific events, etc.
