sdk/log: Fix TestBatchProcessor/DroppedLogs flaky test (#5421) 
Fix #5384

Run of `go test  -count=1000000 -run="TestBatchProcessor/DroppedLogs"`
**Before**:
Failed with either `Condition never satisfied` or panic
**After**:
Passed

First, bytes.Buffer is not thread-safe, so writing log and reading
(`bytes.String()`) caused panic. Added `concurrentBuffer`
Second, fixed flaky test with 4 records:
1. Record goes to `testExporter.Export` function and blocks in this
function because of `ExportTrigger`
(19ee6d4775/sdk/log/exporter_test.go (L87))
2. Record goes to `bufferExporter.input`
(7c5e64cccc/sdk/log/exporter.go (L129))
3. Record goes to `BatchProcessor.q` queue and it could not be enqueued
to export, because `bufferExporter.input` is full
4. Record goes to `BatchProcessor.q` and because of overfill, drops
third record
