Allow SHA-1 in SSL renegotiation tests

Browse Source 
In the TLS test client, allow SHA-1 as a signature hash algorithm.
Without this, the renegotation tests failed.

A previous commit had allowed SHA-1 via the certificate profile but
that only applied before the initial negotiation which includes the
signature_algorithms extension.
