block/gluster: update .help of BLOCK_OPT_PREALLOC option

Add missing 'falloc' among the allowed values of 'preallocation'
option; show it and 'full' only when they are supported.
('falloc' is supported if defined CONFIG_GLUSTERFS_FALLOCATE,
'full' is supported if defined CONFIG_GLUSTERFS_ZEROFILL)
