boards/stm32f746g-disco: add explicit CRYPTO/CODECS deps for dropbear defconfig

nuttx-apps#3557 switches FSUTILS_PASSWD and NETUTILS_DROPBEAR to depend on
CRYPTO, CRYPTO_RANDOM_POOL, NETUTILS_CODECS and CODECS_BASE64 instead of
selecting them. stm32f746g-disco/dropbear must enable these explicitly so
olddefconfig/CI normalize keeps dropbear and FSUTILS_PASSWD enabled.
