[OE-core] [PATCH 1/1] oe_syslog.py: fix for syslog-ng

[Chen Qi]

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 the grep command
to also consider 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 it to actually output the ps information. After the change, it looks like:
| AssertionError: 1 != 0 : No syslogd process; ps -ef output:
| UID        PID  PPID  C STIME TTY          TIME CMD
| root         1     0 28 07:35 ?        00:00:19 /sbin/init
| root         2     0  0 07:35 ?        00:00:00 [kthreadd]
| root         3     2  0 07:35 ?        00:00:00 [kworker/0:0]
...
