LU-16791 utils: ZFS 2.2 const prop args

ZFS 2.2 now expects const char * from certain interfaces in
sys/nvpair.h. I updated the build system to detect if this is the case
and if so update the paramters passed to certain functions in
libmount_utils_zfs.c to account for these changes.

Without this patch, Lustre master would not build with ZFS master and
the 2.2 release candidates.
