perf buildid-cache: Add --purge FILE to remove all caches of FILE

Add --purge FILE to remove all caches of FILE.

Since the current --remove FILE removes a cache which has
same build-id of given FILE. Since the command takes a
FILE path, it can confuse user who tries to remove cache
about FILE path.

  -----
  # ./perf buildid-cache -v --add ./perf
  Adding 133b7b5486d987a5ab5c3ebf4ea14941f45d4d4f ./perf: Ok
  # (update the ./perf binary)
  # ./perf buildid-cache -v --remove ./perf
  Removing 305bbd1be68f66eca7e2d78db294653031edfa79 ./perf: FAIL
  ./perf wasn't in the cache

Actually, the --remove's FAIL is not shown, it just silently fails.

So, this patch adds --purge FILE action for such usecase.

perf buildid-cache --purge FILE removes all caches which has same FILE
path.

In other words, it removes all caches including old binaries.

  # ./perf buildid-cache -v --add ./perf
  Adding 133b7b5486d987a5ab5c3ebf4ea14941f45d4d4f ./perf: Ok
  # (update the ./perf binary)
  # ./perf buildid-cache -v --purge ./perf
  Removing 133b7b5486d987a5ab5c3ebf4ea14941f45d4d4f ./perf: Ok

BTW, if you want to purge all the caches, remove ~/.debug/* .
