perf buildid-cache: Remove unneeded debugdir parameters
Functions related to buildid-cache subcommand use debugdir parameters
for passing buildid cache directory path. However all callers just pass
buildid_dir global variable. Moreover, other functions which refer
buildid cache use buildid_dir directly.
This removes unneeded debugdir parameters from those functions and use
buildid_dir if needed.
