ci(tf-cov-make): remove redundant cloning of tf-m* repo

Optimize the tf-a-coverity job by eliminating redundant
cloning of the tf-m tests and extras repository.
This duplication has become unnecessary as the tf-a-coverity
job already handles the cloning of these repositories.
Additionally, recent TF-A modifications have shifted towards
utilizing the 'main' branches of these repositories, making
the extra cloning step obsolete.
