It seems like a problem with CentOS.  The symbol is used by libguestfs
in several places, eg:

  https://github.com/libguestfs/libguestfs/blob/c5eec6c17b55812d1bcba853999421711ee441eb/lib/info.c#L80

and should be provided by the jansson package:

  $ nm -D /usr/lib64/libjansson.so.4 | grep json_string_length
  0000000000008620 T json_string_length

CentOS 7.2 is quite old, although it seems like the libguestfs version
is from 7.5.  Would it be possible to upgrade to something a bit
newer?  The latest is CentOS 7.8 and it should be a straightforward
upgrade.

If upgrading doesn't help then you should file a bug with the CentOS
bug tracker to tell them that the program has been built incorrectly:
