Fix warning with gcc7/maximum allocation exceeded

Browse Source 
Adds an additional boundary check to the test parameter bytes_arg in
generate_random() in test_suite_psa_crypto.function.

This is to check against a possible underflow, and to avoid a warning,
"argument ... exceeds maximum object size", (-Werror=alloc-size-larger-than)
that GCC 7 generates.
