ci: cirrus: Fix test ranges.

The CirrusCI configuration file was not updated back when the size of the
test matrix was reduced.

CirrusCI jobs were complaining of invalid test ranges for a while but
that slipped through the cracks until commit 0224e45 ("ci: Remove
'--recheck' in CI.") uncovered the failure:

  make distcheck 'CFLAGS= ' -j4 'TESTSUITEFLAGS=-j4 501-1000' RECHECK=no SKIP_UNSTABLE=yes
  [...]
  invalid test group: 1000

At the same time, make sure --recheck is passed to ARM jobs (on
CirrusCI).  These have been always more unstable than other CI jobs.

Fixes: 937a9b5 ("ci, tests: Use parallelization permutations for few jobs")
Fixes: 0224e45 ("ci: Remove '--recheck' in CI.")
