[PATCH] perf annotate: Skip DSOs not found

[Namhyung Kim]

In some data file, I see the following messages repeated.  It seems it
doesn't have DSOs in the system and the dso->binary_type is set to
DSO_BINARY_TYPE__NOT_FOUND.  Let's skip them to avoid the followings.

  No output from objdump  --start-address=0x0000000000000000 --stop-address=0x00000000000000d4  -d --no-show-raw-insn       -C "$1"
  Error running objdump  --start-address=0x0000000000000000 --stop-address=0x0000000000000631  -d --no-show-raw-insn       -C "$1"
  ...
