Add missing dependencies

There are multiple places where the dependencies are
explicitly missing & its working as of today because
of the way the code was organised.

The intent behind this commit is add the missing dependencies
explicitly. This commit fixes :
1. common tests depends on header files in common folder, but
it is not added as a dependency, fixing this by adding libpldmutils
as the dependency.
2. fw-update tests depends on header files in common folder as well,
but it is not added as a dependency , fixing this by adding libpldmutils
as the dependency.
3. requester test code includes header files in the pldmd folder, but
that is not added as a dependency as well, fixing this by adding
include_directories and making it a dependency.
