Those scripts don't actually exist, only a few protocols have the
'software' scripts;

scripts/policy/protocols/ftp/software.zeek
scripts/policy/protocols/ssh/software.zeek
scripts/policy/protocols/http/software-browser-plugins.zeek
scripts/policy/protocols/http/software.zeek
scripts/policy/protocols/smtp/software.zeek
scripts/policy/protocols/mysql/software.zeek
scripts/policy/protocols/dhcp/software.zeek

The default scripts/base/init-default.zeek already contains the @load
statements for the base dnp3 and modbus scripts;

@load base/protocols/dnp3
@load base/protocols/modbus

so you shouldn't have to do any configuration to analyze these protocols.
