load_outdb related tests fail for 2.2.2 & 2.3.0-beta1 on Debian unstable

[sebastic]

It seems the -pre.pl & -post.pl scripts are no longer executed, because the load_outdb tests report an error for the missing table:

ERROR:  relation "raster_outdb_template" does not exist at character 22

To troubleshoot this issue I used the following patch:

+           warn "couldn't run $file"       unless $return;
+       }
     }
 } 

For the load_outdb related tests this reports:

This seems to be caused by . being removed from @INC in perl to fix ​This seems to be caused by . being removed from @INC in perl to fix ​CVE-2016-1238. n.org/tracker/CVE-2016-1238 CVE-2016-1238.

The -pre.pl & -post.pl scripts for loader/ tests aren't executed either, but those tests handle that gracefully when they cannot read the expected files.

attachment:run_test-INC.patch​ adds . to @INC if it's not present, which resolves this issue.

The Debian perl maintainers sent an extensive announcement about this change recently, see:

​Upcoming change to perl: current directory in @INC
