sd-bus: sync kdbus.h (API change: switch to absolute timeouts)

kdbus_msg.timeout_ns now takes an absolute value, based on CLOCK_MONOTONIC,
in order to eventually support automatically restarted syscalls.

Update TODO
fsck: re-enable fsck -l

The -l (lock) has been temporary disabled due to conflict with
udev (https://bugs.freedesktop.org/show_bug.cgi?id=79576)

The problem is fixed since util-linux v2.25 (Jul 2014).
README: simplify documented dependency on util-linux

we stritcly require features from util-linux v2.25, such a new version
is not optional, hence document this.

sd-bus: assert clock_gettime()'s return value

Don't handle clock_gettime() errors gracefully but use assert_se().
networkd: Fix a couple of typos
resolved: simplify detection of packets from the loopback device

We can simplify our code quite a bit if we explicitly check for the
ifindex being 1 on Linux as a loopback check. Apparently, this is
hardcoded on Linux on the kernel, and effectively exported to userspace
via rtnl and such, hence we should be able to rely on it.
