build: use valgrind client request to detect undefined memory usetmp-valgrind-memcheck
This tightens the check introduced in
ac2f71b892d13a7ab4cc39086eef179042c7e23c, by using the valgrind client
request to explicitly mark the "uninitialized but initialization is
needed before use" regions. With this patch and the
fix (c01011c2d8533dbbbe754e49e256c109cb848d0d) reverted, you will see
the following error when running dtls_hello_random_value under
valgrind:
$ valgrind ./dtls_hello_random_value
testing: default
