test/evp_test: Test if EVP_DigestSign() set signature's length.

Browse Source 
Increase the signature's length, that is passed to EVP_DigestSign(). The
implementation should set this parameter back to the actual length, that
has been written.

This (oneshot_digestsign_test_run()) fails for the ed25519/ ed448
implementation of s390 prio the fix. The change in digestsign_test_run()
follows the same pattern and is for collecting bonus points.
