Add permissions to modify raw_syscall filters.
These are to be used by traced in order to support tracing only a subset
of all syscalls when using raw_syscall ftrace events. Currently, the
associated files are only accessible in userdebug via selinux, so the
corresponding chmods are userdebug-only too.
Test: locally on-device with perfetto
