zabbix: drop unwanted file and wrong BUILD_VARIANT

cspell.json was accidentally include in a previous commit, so remove it.

VARIANT is to be used in package definitions, and BUILD_VARIANT
for checking which VARIANT is currently being built. BUILD_VARIANT was
incorrectly used in a package definition, so we fix that.
