perf inject: Close inject.output on exit

Browse Source 
ASan reports a memory leak when running:

  # perf test "83: Zstd perf.data compression/decompression"

which happens inside 'perf inject'.

The bug is caused by inject.output never being closed.

This patch adds the missing perf_data__close().
