remove usage of WANT_TRANSACTION option

The feature to disable transactions is not used anywhere in openbmc
and it is just making the build system more complicated than necessary.

Will follow up with removing entirely from configure.ac after the recipe
is updated with this change so that we do not have any co-req with the
recipe updates.
