doc: add dependency on vars.texi

Noticed missing target directory dependency as a build failure in
`make --shuffle` mode (added in https://savannah.gnu.org/bugs/index.php?62100):

    Making all in doc
    make[1]: Entering directory '/build/heimdal/doc'
      MAKEINFO hx509.info
    hx509.texi:15: @include: could not find vars.texi
    hx509.texi:31: warning: undefined flag: PACKAGE_VERSION
    hx509.texi:186: warning: undefined flag: PACKAGE_VERSION
    make[1]: *** [Makefile:622: hx509.info] Error 1 shuffle=1656683556

The change moves vars.texi to BUILT_SOURCES to guarantee it's
presence when .info files start the build.
