Add CRC32 support to the sig-handover tests

Initialisation of T10-DIF signature domain has been removed from
the sig_test_base fixture. Now an abstract sig_domain is used in
sig_test_base. So we can use the same tests for different
sig_domains. Two implementations of sig_domain was added:
 * T10-DIF
 * CRC32
