syslog-ng2 -- startup directory leakage in the chroot environment

Description:

Florian Grandel reports:

I have not had the time to analyze all of syslog-ng code. But by reading the code section near the chroot call and looking at strace results I believe that syslog-ng does not chdir to the chroot jail's location before chrooting into it.

This opens up ways to work around the chroot jail.
