  -----------
  [libc][realpath] Follow symlinks

This commit updates realpath to call readlinkat on symlinks during path resolution. In order to do, it updates `PendingPath` to store a `cpp::string` that is prepended with a symlink target when resolved. This could be more efficient by using a `PATH_MAX` buffer and storing the path at the end of the buffer, but using a `cpp::string` avoids the pointer arithmetic and manual memory management that comes with that approach.
