[PATCH 45/59] Remove invalid tzset tests from tst-bz29951.c

[Paul Eggert]

* timezone/tst-bz29951.c (set_timezone):
Do not test errno after tzset, as its value is unspecified then.
(do_test): Do not test daylight or timezone after tzset, as their
values are unspecified with geographical TZ.  See Austin Group
Defect 1816 <https://www.austingroupbugs.net/view.php?id=1816>.
