Ondrej Mosnacek c5a513f55d tracing: Fix permissions for the buffer_percent file ...

commit 4f94559f40 upstream.

This file defines both read and write operations, yet it is being
created as read-only. This means that it can't be written to without the
CAP_DAC_OVERRIDE capability. Fix the permissions to allow root to write
to it without the need to override DAC perms.
