Ignore cases related to external_fts

[avamingli]

Plan Seq scan on gp_segment_configuration would be replaced by Function Scan on gp_get_segment_configuration when external_fts is on.

Inconsistence between CIs will cause such cases to fail. Ignore these as workaround.

I think regress has a feature of automatically matches multiple expected file and choose the one generating the shortest diff, we can have two rpt_joins.out named rpt_joins_1.out and rpt_joins_2.out, one for external_fts=on one for =off. regress could choose between them automatically (this is how we fix xml.out in #206). now that we already fixed log and results uploading in #240 we can directly download CI output and put it as rpt_joins_2.out and everything should works fine again.

You are right, and we have a xxx_external_fts.out technique to handle that.
We have a internal discussion, the conclusion are:
xxx_external_fts.out could resolve this, but we only have 2 lines diff and have to copy 2000 lines for a new file.
The root cause is inconsistent GUCs between Github and Release CI, a external_fts CI will be added for Github later.
This is a workaround, we will take such cases back after that CI enabled.
