    devel/llvm17: fix build with clang 21
    
    Recent versions of clang complain about explicit copy constructors,
    leading to errors similar to:
    
        /wrkdirs/usr/ports/devel/llvm17/work-default/llvm-project-17.0.6.src/llvm/tools/sancov/sancov.cpp
        /wrkdirs/usr/ports/devel/llvm17/work-default/llvm-project-17.0.6.src/llvm/tools/sancov/sancov.cpp:521:42: error: chosen constructor is explicit in copy-initialization
          521 |     return SpecialCaseList::createOrDie({{ClIgnorelist}},
              |                                          ^~~~~~~~~~~~~~
        /usr/include/c++/v1/string:1153:64: note: explicit constructor declared here
         1153 |   _LIBCPP_HIDE_FROM_ABI _LIBCPP_CONSTEXPR_SINCE_CXX20 explicit basic_string(const _Tp& __t) {
              |                                                                ^
        /usr/include/c++/v1/__vector/vector.h:276:91: note: passing argument to parameter '__il' here
          276 |   _LIBCPP_CONSTEXPR_SINCE_CXX20 _LIBCPP_HIDE_FROM_ABI vector(initializer_list<value_type> __il) {
              |                                                                                           ^
    
    In this case, `ClIgnoreList` is an instance of `cl::opt`, not a
    `std::string` as expected. Use `getValue()` to get the actual
    `std::string` value.
