Add the profiling settings for tests explicit.

Many profiling related tests make assumptions on the profiling settings,
e.g. opt_prof is off by default, and prof_active is default on when opt_prof is
on.  However the default settings can be changed via --with-malloc-conf at build
time.  Fixing the tests by adding the assumed settings explicitly.
