devel/poco: fix build with libc++ 19
As noted in the libc++ 19 release notes [1], std::char_traits<> is now
only provided for char, char8_t, char16_t, char32_t and wchar_t, and any
instantiation for other types will fail.
This causes devel/poco to fail to compile with clang 19 and libc++ 19,
resulting in errors similar to:
/usr/include/c++/v1/string:820:42: error: implicit instantiation of undefined template 'std::char_traits<unsigned char>'

243 | inline void swap<Poco::Data::BLOB>(Poco::Data::BLOB& b1, Poco::Data::BLOB& b2) noexcept
| ^
In this case it is enough to only enable the LOB constructor from
std::basic_string when the type is plain char.
