rsync 3.10 now defaults to human readable output, with sizes being
printed with a separator between group of 3 digits.
This broke our download progress parser.

We can fix this by using the --no-human-readable command line option,
to get the old rsync progress output format.

This option already existed in older rsync versions (tried in Mageia
2), so this change should be safe to include in backports of urpmi to
older distributions.

(testsuite) adapt to new URPM predictible behaviour

it was previously relying on the following fixed hash order:

$ perl -MData::Dumper -e 'warn Dumper [ keys {'rr1', 'rr1', 'rr2',
'rr2'} ]; \
warn Dumper [ keys {'bb1', 'bb1', 'bb2', 'bb2-1'} ]'
$VAR1 = [
          'rr2',
          'rr1'
        ];
$VAR1 = [
          'bb1',
          'bb2'
        ];

(eg: running testsuite in a chroot)
