When using syslog-ng as the syslog provider, oe_syslog test case fails
because it cannot find the syslog daemon. This is because it greps for
'syslogd' but syslog-ng's daemon is 'syslog-ng'. So fix it to check both
'syslogd' and 'syslog-ng'.
Also, when the test case fails, what I get is:
| AssertionError: 1 != 0 : No syslogd process; ps output:
<empty here>
This does not help user. The output is actually from the 'PS | GREP' command.
And when the 'PS | GREP' command fails, the output is always empty. So also fix
this problem. After the change, it looks like:
| AssertionError: False is not true : No syslog daemon process; ps output:
| PID USER VSZ STAT COMMAND
| 1 root 16476 S {systemd} /sbin/init
| 2 root 0 SW [kthreadd]
| 3 root 0 IW [kworker/0:0]
