Remove more warnings from tests

GCC12 catches various issues in tests at compile time that we want to
catch at runtime. Also glibc 2.34 deprecated various mallinfo related
functions. Add the relevant -Wno-foobar flags to those tests.  In one
case, unit_oset.c, the warning was correct and the uninitialized
variable was explicitly set.
