vpnor: table: Handle alignment warning

The static_assert() isn't enough for g++-9, do the slow but correct
thing and copy the data into a container with the correct alignment.

Resolves:

In file included from vpnor/table.cpp:11:
./vpnor/table.hpp: In instantiation of ‘openpower::virtual_pnor::checksum_t openpower::virtual_pnor::details::checksum(const T&) [with T = pnor_partition_table::<unnamed struct>; openpower::virtual_pnor::checksum_t = unsigned int]’:
vpnor/table.cpp:52:50:   required from here
./vpnor/table.hpp:66:10: warning: converting a packed ‘const pnor_partition_table::<unnamed struct>’ pointer (alignment 1) to a ‘const unsigned int’ pointer (alignment 4) may result in an unaligned pointer value [-Waddress-of-packed-member]
   66 |     auto begin = reinterpret_cast<const checksum_t*>(&data);
      |          ^~~~~
