[PATCH 2/2] init-db: change --template type to OPTION_FILENAME

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

OPTION_FILENAME has some magic behind the scene, like prefixing which is
useless for init-db. The $HOME expansion though does come handy and
makes --template more consistent with the rest (both env and config var
get $HOME expansion).
