This includes:
* an eBPF object built with a newer kernel (4.14)
* an increased threshold for guessing offsets, which is necessary for
the eBPF tracer to work on Google's Container-Optimized OS (used by
GKE)

bump tcptracer-bpf version and use it to fix race
...
We defer starting the ebpf tracer until we've set the global var which
is referenced by the callback functions. Previously the var could be
unset when the callbacks are invoked, resulting in a segfault.
Fixes #2687 .

It will help to get missing kretprobe events during the ebpf tracker
initialization and missing connect & accept events, specially visible on
single-cores:
- https://github.com/weaveworks/tcptracer-bpf/pull/36
- https://github.com/iovisor/gobpf/pull/39
It makes use of a Linux patch that should be in Linux >= 4.12
(unreleased yet): https://github.com/iovisor/bcc/issues/1072#issuecomment-289777787
It falls back gracefully on current/older Linux kernels.
The new gobpf vendoring also includes other small fixes such as error
handling.

We found out we were losing kretprobes sometimes because maxactive was set too
low[1]. This problem was more apparent in our GCE test environment because
the kernel was configured with `CONFIG_PREEMPT` not set and we're running
single-core VMs (see https://github.com/weaveworks/tcptracer-bpf/issues/24 for
more details).
Unfortunately, we can't set the maxactive explicitly from userspace. Alban
submitted a kernel patch to allow this[2].
This bumps tcptracer-bpf to include a workaround[3] for this issue in the
guess-offsets phase.
