Update concat_ice_daily to support more cice variable filenames

[anton-seaice]

We need to fix this line

https://github.com/COSIMA/om3-scripts/blob/efb2167a1ecf8ef8355c9fa964f01319679e5bab/payu_config/archive_scripts/concat_ice_daily.sh#L54

to allow more variety of filenames:

(e.g. access-om3.cice.1day.????-??-01.nc )

and we should also check that the "output" filename is not overwriting an existing file.
