Description
The Java_sun_security_pkcs11_wrapper_PKCS11_C_1Sign function in src/jdk.crypto.cryptoki/share/native/libj2pkcs11/p11_sign.c should check for and handle CKR_BUFFER_TOO_SMALL, much like Java_sun_security_pkcs11_wrapper_PKCS11_C_1SignFinal already does.

Add the handling for CKR_BUFFER_TOO_SMALL error for C_Sign(...). However, this handling is coded based on PKCS#11 v3.0 spec for completeness handling. Existing buffer size is good enough for current list of supported signature algorithms, so it can't be tested by regression test. Thus the @noreg-hard label.
