lib/test: Cater for gcc-12.2.0.

Browse source 
These inexplicably avoid segfaults with gcc-12.2.0.

* lib/tests/posix/50-open-read.c (main)[__GNUC__ > 11]: Use malloc
instead of local allocated string.
* lib/tests/scaffold/7i-struct-struct.c (main)[__GNUC__ > 11]:
Initialize all fields of struct.
* lib/tests/scaffold/t.c (main): Likewise.
