Point to integration instead of master branch for TF-A project

By default, jobs, specially tf-daily and derivatives (tf-main and
tf-coverity), should point to the project integration branch instead
of master. Although test level jobs (L1 and L2) are not usually
triggered manually nor intended for testing the integration branch,
for consistency, point these to the latter branch.
