perf buildid-cache: Remove extra debugdir variables

There's no need to copy over the buildid_dir into separate variable with
no change.

This is leftover from commit:
  45de34bbe3e1 perf buildid: add perfconfig option to specify buildid cache dir

that added global buildid_dir variable that holds cache directory, but
did not cleanup the debugdir copies.
