[DEVEL] [PATCH 2.6.18] Fix syslog() issues in LTP

[Vitaliy Gusev]

Patch from Vitaliy Gusev <vgusev at openvz.org>
Fix syslog issues for LTP testscase. Problem was that LTP test calls syslog(2) with wrong arguments  and waiting
for a error but syslog() returns zero.

Fixes: http://bugzilla.openvz.org/show_bug.cgi?id=584
