samples: matter: Fix WiFi release build by disabling RAM PWRDWN

ArekBalysNordic · rlubos · commit 9397a22115ae · 2024-12-12T10:18:18.000+01:00
We must disable RAM powerdown library due to wrong WiFi
configuration. It selects COMMON_LIBC_MALLOC which cannot be
enabled together with RAM_POWER_DOWN_LIBRARY.
