[LTP] [PATCH 1/1] ioctl02.c: check for struct termio

[Petr Vorel <petr.vorel@gmail.com>]

Test is meant to use legacy struct termio, so we need to check for it.

Signed-off-by: Petr Vorel <petr.vorel@gmail.com>

Tested: https://travis-ci.org/pevik/ltp/builds/643099597

NOTE: also rewriting other tests to new API which will use LTP_CHECK_TERMIO
(ioctl02.c and ptem01.c).

Kind regards,
Petr
