Includes a copy of in

https://publicsuffix.org/list/effective_tld_names.dat
in httpclient5/src/test/resources/org/publicsuffix/list/effective_tld_names.dat

Cleanly separate the concerns of which file to copy and whether to
filter it or not by using two <resource> elements:

- We want the .properties file copied and filtered. The git master
version causes only the properties file to be copied, the .dat file is
not copied.
- We want to the .dat file copied but not filtered.
