[dak/master] daklib/filewriter.py: change default compression to gzip and xz

[Ansgar Burchardt <ansgar@debian.org>]

Change the default compression for Packages and Sources indices to gzip
and xz (from gzip and bzip2). This does not affect existing suites with
indices_compression set in the database.
