file.c: get rid of useless conversion
* file.c (rb_file_s_stat): File.stat does not accept an IO
object as trying conversion to path name string first. skip
conversion to IO and try stat(2) only.
file.c: realpath on special symlink
* file.c (realpath_rec): fallback to symlink path when it is
accessible but the link target is not actual entry on file
systems. [ruby-dev:50487] [Bug #14557]
