Subject: [PATCH] perf test: Remove the temporary trace record file when the test fails

Even if there's no nanosleep in the trace record file, it doesn't mean
the file itself doesn't exist. Remove the temporary file since the test
frequently fails on my machine and leaves behind many uncleaned
temporary files.
