Refactor ext/POSIX/t/termios.t

* Only import termios.h functions and constants from POSIX
* Loop over STDIN, STDOUT, STDERR instead of duplicating code.
* Avoid a needless defined? test, as isa_ok() handles undef.
* Switch to done_testing(), which also allows @getters to be inlined and
  eliminated.
* The various get*() methods return integer values, so check this.
* Enable warnings.
