xmlto: backport a patch to fix build with gcc-14 on host

* need to add dependency on flex-native because now when the
  .l file is modified by the .patch file it will try to regenerate
  the c code and fail:

| make[1]: Entering directory 'work/x86_64-linux/xmlto-native/0.0.28-r0/build'
| /bin/bash ../xmlto-0.0.28/ylwrap ../xmlto-0.0.28/xmlif/xmlif.l .c xmlif/xmlif.c -- /bin/bash 'work/x86_64-linux/xmlto-native/0.0.28-r0/xmlto-0.0.28/missing' flex
| work/x86_64-linux/xmlto-native/0.0.28-r0/xmlto-0.0.28/missing: line 81: flex: command not found
| WARNING: 'flex' is missing on your system.
|          You should only need it if you modified a '.l' file.
|          You may want to install the Fast Lexical Analyzer package:
|          <https://github.com/westes/flex>

* backport
  https://pagure.io/xmlto/c/32376c053733c6c0ebaca3c25c0725509342fdf3?branch=master
  as well, so that patched xmlif/xmlif.c is newer than xmlif/xmlif.l and the build
  won't try to regenerate it with flex as that leads to random build failures reported
