Removed allocate_failure_test1 from equeue tests

This tests doesn't run on some MCUs with low RAM. According to @geky:

"We may want to omit this test (allocate_failure_test1) for now. It has
had other problems such as overflowing stacks, and allocation failure is
also tested by allocate_failure_test2."
