The validate_mongocryptd script checks that buildvariants that push the mongocryptd binary also add the variant to a list. However, the script currently does this for all buildvariants, including ones that are only for testing and do not contain a push task. This is causing problems with some dynamic variants we are trying to create. The script could also check for a push task.

As a Server Engineer,
I want validate_mongocryptd to check for a push task,
So that variants that do not push mongocryptd do not need to be included in the variant list.

AC:

• Variants the do not contain a push task will not fail to validate_mongocryptd if they are not included in the list of variants.
