Fix std::filesystem

Browse source 
This change makes a second pass, at fixing the errno issue with libcxx's
filesystem code. Previously, 89.01% of LLVM's test suite was passing and
now 98.59% of their tests pass. Best of all, it's now possible for Clang
to be built as a working APE binary that can to compile the Cosmopolitan
repository. Please note it has only been vetted so far for some objects,
and more work would obviously need to be done in cosmo, to fix warnings.
