stty: portability: accommodate CIL

* src/stty.c (main): Declare locals "mode" and "new_mode" to be static
to ensure that each is initialized to zero, *including* all padding.
While gcc clears padding of a local automatic initialized to "{ 0, }",
CIL does not, and the C99 standard is not clear on this issue.
Reported by Edward Schwartz.  See http://bugs.gnu.org/11675 for details.
