tracing: Rename 'lockdep' event subsystem into 'lock'

Browse source 
Lockdep events subsystem gathers various locking related events
such as a request, release, contention or acquisition of a lock.

The name of this event subsystem is a bit of a misnomer since
these events are not quite related to lockdep but more generally
to locking, ie: these events are not reporting lock dependencies
or possible deadlock scenario but pure locking events.

Hence this rename.
