This reverts commit e2c27194fc.
This change breaks Android userspace tools (tracepoint bpf programs,
simpleperf, atrace, perfetto, ...) that assume access to tracefs.
On Android T and S (QPR2) this is fixed by adding a gid mount option
in userspace, for devices with older kernels the permission change
needs to be reverted.
