landlock: Rename "ptrace" files to "task"

Browse Source 
ptrace.[ch] are currently only used for the ptrace LSM hooks but their
scope will expand with IPCs and audit support.  Rename ptrace.[ch] to
task.[ch], which better reflect their content.  Similarly, rename
landlock_add_ptrace_hooks() to landlock_add_task_hooks().  Keep header
files for now.
