rgw: temporarily use std::vector in place of static_vector of Boost.

We want to use boost::container::static_vector to avoid dynamic
memory allocations. However, Boost on some platforms we support
doesn't offer this container yet.

The patch can be safely reverted when we get modern enough Boost
on all our platforms.
