hostname-wordlist: replace "petnames" wordlists

The petnames wordlist added in [1] is Apache-2.0 and this
causes problems with the distribution of systemd as the
GPL-2 and Apache-2.0 are considered incompatible by the FSF.

So this commit replaces the previous wordlist with
a new one:
- weather (basic english weather adjectives)
- colors (basic english color names)
- worlds (planets, moons, minor bodies of the solar system)

All common vocabulary and compiled for this project, not taken
from anywhere.

An example with the new list:
- wintry-rust-dione-9393
- warm-yellow-saturn-39f9

The "worlds" are picked on the following principles:
- well-known
- memorable
- short(ish)
- cool

This is why e.g. we have "thetis" (an astroid) instead of
"tethys" (a moon): easier to spell and more well known.

 Origin
 ------
 
-These are the "small" word lists taken from the petname project
+Compiled for systemd from common vocabulary and standardized names rather than
-(https://github.com/dustinkirkland/petname), distributed under the Apache
+imported from an existing word list.
-License 2.0. Distributions are encouraged to ship larger lists (petname also
+
-provides "medium" and "large") for a bigger name space.
+    weather  Everyday English weather adjectives
+    colors   Basic English color names
+    worlds   The planets, moons and minor bodies of the solar system
+
+The lists are deliberately short: they are picked for being easy to recognize,
+read out over the phone and type from memory, while the '?' wildcards carry the
+entropy.
