sun partition tables: add support for RAID partition types

This patch enables RAID as a supported partition type on Sun disk
layouts, commonly found/used on SPARC hardware. It has been tested
on Aurora SPARC Linux (and Fedora SPARC). I have no idea if Solaris
supports Software RAID or not...

Along with the code change, I wrote a test case that checks if the
RAID partition type is supported on sun disk labels.

* libparted/labels/sun.c [_SunPartitionData] (is_raid): New member.
(sun_read): Initialize the ->is_raid member.
(sun_partition_new): Clear is_raid, like all the other members.
(sun_partition_duplicate): Propagate the is_raid member.
(sun_partition_set_system): Make sun_data->type reflect is_raid.
(sun_partition_set_flag): Also initialize ->is_raid.
(sun_partition_get_flag): Handle PED_PARTITION_RAID.
(sun_partition_is_flag_available): Likewise.
* tests/t4000-sun-raid-type.sh: New file.
* tests/Makefile.am (TESTS): Add t4000-sun-raid-type.sh.
