Fix: Sleeping function called from invalid context

It affects system call instrumentation for accept, accept4 and connect,
only on the x86-64 architecture.

We need to use the LTTng accessing functions to touch user-space memory,
which take care of disabling the page fault handler, so we don't preempt
while in preempt-off context (tracepoints disable preemption).

Fixes #1111

Fix: handle missing ftrace header on v4.12

Properly handle the case where we build against the distro headers of a
kernel >= 4.12 and ftrace is enabled but the private header is
unavailable.

Fix: pid tracker should track "pgid"

The "pid" notion exposed by LTTng translates to the "pgid" notion in the
Linux kernel. Therefore using "current->pid" as argument to the PID
tracker actually ends up behaving as a "tid" tracker, which does not
match the intent nor the user-space tracer behavior.
