MBEDTLS_PSA_INJECT_ENTROPY: Make sure the seed file exist when running tests

Browse source 
The seed file must exist before running tests. Because the location is
somewhat platform- and configuration-dependent, and to be friendly to
developers who run test suites individually and aren't familiar with this
feature, rely on the test framework code rather than on test scripts to
create the seed file.
