Jason Rhinelander bfe0221b8c Disable std::filesystem on macOS targetting <10.15
macOS flat out refuses to compile if you touch std::filesystem when
targetting macOS < 10.15 (to be able to deploy a binary to older macOS
versions).

This disables the std::filesystem support when in C++17 mode with such a
target.
