Title: FIX: yama ptrace scope on ubuntu

Yama prevented the spawned gdb to ptrace the dying cvmfs process on ubuntu. This only occured for private mount points, because cvmfs cannot re-gain root permissions which would override yama-rules.

This uses `prctl(PR_SET_PTRACER, PR_SET_PTRACER_ANY)` to create an exception for cvmfs.
