Make krb5 and open checks work if forking is disabled

When CK_FORK is set to 'no' the fixtures are executed for every new test
inside of the same process. Global variables must be set to the expected
values by the fixtures.

check_and_open-tests.c: the filename template for mkstemp() was a
globally defined character string. After the first call to mkstemp() the
trailing XXXXXX are substituted by random values, a second call to
mkstemp() with this character string fails. This patch initialize the
filename template before mkstemp() is called with the help of strdup()
and the memory is freed in the teardown fixture.

krb5_utils-tests.c: this patch sets the just freed global talloc context
to NULL to make a consistency check in the setup fixture pass.
