[cloud]Ensure SGs in default VPCs get default egress rule (#38018)

SGs created when a VPC ID was not specified would not necessarily
get the default egress rule, even when no explicit egress rules
were set.

Add some checks for egress rules in results from existing tests

(cherry picked from commit 98b29f8ad6)
