oe_syslog.py: fix for syslog-ng

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]
...
