package/libplist: fix static link

- libplist depends on libm and optionally on zlib and libiconv (via
  libxml2), so add a patch fixing the build-system that way
- disable shared object build when BR2_PREFER_STATIC_LIB is set

+Subject: [PATCH] cmake: make sure the libxml2 module correctly set all ldflags
+ in case of static link
+
+libxml2 dependencies against zlib and libiconv are optional.
+
+When executing a statically linked build, the default libxml2 CMake
+module fails to get the libxml2 dependencies (both the required and
+optional ones); so the link phase fails.
+
+However, pkg-config correctly gives these dependencies, even for static
+build. So, extend the libxml2 library list with what the pkg_check_modules
+CMake primitive (which will uses pkg-config) found.
