uhd: Replace boost::regex with std::regex

boost::regex was a requirement until the minimum version of gcc was
increased. Since it is at version 5.3 now, using Boost.Regex is no
longer necessary.
This change is a pure search-and-replace; Boost and std versions of
regex are compatible and use the same syntax.
