use mode_t where applicable (instead of int)

mode_t is the correct type for these syscalls and it can be
easier-to-understand.  It may also help portability to future
platforms and improve type checking.

* dir.c (dir_s_mkdir): use mode_t for mkdir(2)

* file.c (chmod_internal): use mode_t for chmod(2)
  (rb_file_s_chmod): s/int/mode_t/
  (lchmod_internal): ditto, deref pointer as in chmod_internal
  (rb_file_s_lchmod): pass pointer as in rb_file_s_chmod
  (rb_file_s_rename): use mode_t for umask(2)
