[OE-core] [PATCH 2/2] oeqa/systemd get runtest target boot time and log

oeqa.runtime.systemd.SystemdJournalTests.test_systemd_boot_time
this test will query the target boot time from journactl and will
print it to the output, if the time is obtained, the test passes

it then compares the boot time against the default systemd's
timeout TimeoutStartSec and if the boot time is greater than the
it will print it too

this test prints the startup time in the test log like:
...
test_systemd_boot_time (oeqa.runtime.systemd.SystemdJournalTests) ...
Startup finished in 6.922s (kernel) + 52.089s (userspace) = 59.011s.
