Work around missing MSAN instrumentation

Browse Source 
Let us skip the recently added test main.mysql-interactive if
an instrumented ncurses library is not available.

In InnoDB, let us work around an uninstrumented libnuma, by
declaring that the objects returned by numa_get_mems_allowed()
are initialized.
