CHROMIUM: config: Enable AES-GCM mode for IPsec

CONFIG_CRYPTO_AES=y by itself does not enable GCM mode on non-x86
platforms, so if strongSwan negotiates aes128gcm16 for ESP, ARM kernels
with CONFIG_CRYPTO_GCM disabled will return -ENOSYS.  Enabling
CONFIG_CRYPTO_GCM fixes this.

BUG=chromium:707139
TEST=manually connect to a Sophos UTM gateway on veyron_minnie
