[Buildroot] [PATCH 1/1] package/s390-tools: add libxml2 optional dependency

[Fabrice Fontaine]

libxml2 is an optional dependency which is enabled by default since
version 2.17.0 and
https://github.com/ibm-s390-linux/s390-tools/commit/56fecf1832c3ebc4626ddf5c598762833c362d5e

Also set PATH to avoid the following build failures related to
curl-config and xml2-config:

/bin/sh: 1: curl-config: not found
Error: libcurl is not built with the OpenSSL backend
make[2]: *** [Makefile:54: check-dep-libekmfweb] Error 1

Fixes:
