Update /rom/ca-bundle.crt in custom firmware

[ASAT]

You can update it manually this way.

# my Linux Mint 13 build box
sudo apt-get update
sudo apt-get install ca-certificates
cp -pf /etc/ssl/certs/ca-certificates.crt ~/asuswrt-merlin/release/src/router/rom/others/ca-bundle.crt

OR, copy it automatically in the ASUS rootprep script during the custom firmware build. I always forget about it.
~/asuswrt-merlin/release/src/router/others/rootprep.sh
~/asuswrt-merlin/release/src/router/others/rootprep_arm.sh
