Fix tzname redefinition in MS-Windows
    
    Problem reported by Ian Abbott in:
    http://mm.icann.org/pipermail/tz/2016-February/023289.html
    * localtime.c (tzname): Don’t define if HAVE_POSIX_DECLS,
    as causes the Microsoft compiler to complain that tzname
    is redeclared without dllimport.
    * localtime.c, private.h (altzone): Do define even if
    HAVE_POSIX_DECLS, since this is not a POSIX-specified variable.
