perl: Makefile.PL: Fix _PATH_LOG for deterministic

It checks host's path such as /dev/log and uses it, this doesn't make sense for
cross build, and it causes undeterministic, for example, the contianer os
usually doesn't have /dev/log which leads to a different build result since
other host usually has /dev/log, so make it always use the default value to fix
the issue.
