XFAIL: libcpp-no-deduction-guides in libcxx/test/std/strings/basic.st…

…ring/string.cons/iter_alloc_deduction.fail.cpp

Summary: Refactor the previous version method of marking each apple-clang version as UNSUPPORTED and just XFAIL'ing the libcpp-no-deduction-guides instead.  This brings this test inline with the same style as iter_alloc_deduction.pass.cpp
