hostname_pick_word() used to seek around in the wordlist file and read individual lines with read_line()/read_stripped_line(). Instead, slurp the whole file into memory use offset arithmetic. The wordlists are small, so reading them entirely is faster and there is really no reason to do the complicated thing. The new code is 15% faster (the slow parts are the hashing and chaseat, they actually dominate over the reading of the data). The "raced with truncation" case is gone, since the buffer is a consistent snapshot of the file. The random offsets derived from the machine ID are unchanged, so the picked words stay the same.
