ANDROID: Revert "tracing: Disable "other" permission bits in the tracefs files"

This reverts commit 4e4f6e33.

The file permission changes break android userspace tools that depend on
tracefs on device with older platform release (Android 12/12L).

The removal of other bits from tracefs directory permissions are reverted in android13 kernels, so also revert the change for file permission bits. android14 kernels will align with upstream tracefs.
