textproc/wv: fix build with clang 15
During an exp-run for llvm 15 (see bug 265425), it turned out that
textproc/wv failed to build with clang 15:
wvSummary.c:104:17: error: incompatible integer to pointer conversion initializing 'const GValue *' (aka 'const struct _GValue *') with an expression of type 'int' [-Wint-conversion]
GValue const *val = gsf_doc_prop_get_val (prop);
^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
wvSummary.c:146:21: error: incompatible integer to pointer conversion initializing 'GsfDocMetaData *' (aka 'struct _GsfDocMetaData *') with an expression of type 'int' [-Wint-conversion]
GsfDocMetaData *meta_data = gsf_doc_meta_data_new ();
^ ~~~~~~~~~~~~~~~~~~~~~~~~Those functions are declared in <gsf/gsf-doc-meta-data.h>, but that
header is not included in wvSummary.c.
