testlib: Extend existing *_opts in extra_*_opts
Previously we'd override the existing {run,hc} opts in
extra_{run,hc}_opts, which caused flakiness in T1969, see #17712.
extra_{run,hc}_opts now extends {run,hc} opts, instead of overriding.
Also we shrank the allocation area for T1969 in order to increase
residency sampling frequency.
Fixes #17712
