analyze: fix condition for pretty printing kernel time

On target boards without RTC, `t->kernel_time` is 0 or 1 usec.
`systemd-analyze` reads this value over D-Bus from
`org.freedesktop.systemd1.Manager`, property `KernelTimestamp`.

The issue is: if `t->kernel_time` is 0, `systemd-analyze` does not print
the kernel time:

~~~~
$ systemd-analyze
Startup finished in 1.860s (userspace) = 5.957s
~~~~

This commit fixes the misbehaviour:

~~~~
$ systemd-analyze
Startup finished in 3.866s (kernel) + 2.015s (userspace) = 5.881s
~~~~

Fixes #7721.
