[vcpkg] fix 7616

There's a bug in `std::experimental::filesystem::status` on
libstdc++ -- it incorrectly sets its `error_code` when a file
doesn't exist, or when a path doesn't exist. In order to get
around this, `error_code` was cleared when the file doesn't exist,
but it was not cleared when the path didn't exist.

Note: in this case, I say "the file doesn't exist" when, if you
look up "a/b/c", "a/b" exists but "c" doesn't. I say "the path
doesn't exist" when, if you look up "a/b/c", either "a" or "a/b"
doesn't exist.
