    Add FILESYSTEM_MAP[FS_UNALLOCATED] entry
    
    When displaying an unallocated partition
    Win_GParted::set_valid_operations() calls GParted_Core::get_fs() with
    parameter FS_UNALLOCATED.
    
    Before this change, get_fs() would fail to find file system capabilities
    set for FS_UNALLOCATED and construct a not supported capabilities set
    and return that.
    
    Afterwards, find_supported_filesystems() creates a not supported
    capabilities set from the NULL pointer for FS_UNALLOCATED and adds this
    entry into the FILESYSTEMS vector.  Then get_fs() finds that not
    supported capabilities set for FS_UNALLOCATED in the FILESYSTEMS vector
    and returns that.
    
    This makes no functional difference.  It just seems right as other
    unsupported but used file system types have entries in FILESYSTEM_MAP.
