perf inject: Close inject.output on exit

Browse source 
commit 02e6246f5364d5260a6ea6f92ab6f409058b162f upstream.

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().
