Introduced mbedtls_rsa_rsassa_pss_sign_ext(..., saltlen, ...)

extension of mbedtls_rsa_rsassa_pss_sign() with an extra argument
'saltlen' which allows to inject the length of the salt to the function,
as opposed to the original function which internally computes the
maximum possible salt length. If MBEDTLS_RSA_SALT_LEN_ANY is passed
the function falls back to the the original behaviour. The original
function mbedtls_rsa_rsassa_pss_sign() can simply defer to it.

This allows to make some CAVP PSS generation tests that require the use
of a salt length which is smaller that the hash length.
