all.sh: rationalize relative path usage
In preparation for adding tf-psa-crypto/test/scripts/all.sh which will
run from tf-psa-crypto.
Use paths relative to the currently sourced file when including common
files (ie, those that will soon be moved to the framework). Otherwise,
use paths relative to the current directory, aka project's root.
Document that test/script/all.sh must be invoked from the project's root
(that was already the case, but implicit so far).
