Fix trace naming due to an overwrite permission issue with root permissions

When adbd was started as root, the trace was owned by 'root' user.
If, afterwards, adbd started to record a trace with 'shell' permissions,
it would fail, because it doesn't have the permissions to overwrite the
trace in the output directory.

Now, after having readed a trace, we always try to delete it.
This deletion will succeed only for 'root' users, and fail for 'shell'
users. This will solve the case described before.
