Disable mem leak checking for the self test lock

Disable mem leak checking for the self test lock

The fips self test lock is deallocated in platform specific ways that may
occur after we do mem leak checking. If we don't know how to free it for
a particular platform then we just leak it deliberately. So we
temporarily disable the mem leak checking while we allocate the lock.
