Fix build breakage in gdb/xml-support.c
The buildbots are showing that the previous change to
xml_fetch_content_from_file causes __wur warnings/errors:
../../binutils-gdb/gdb/xml-support.c: In function gdb::unique_xmalloc_ptr<char> xml_fetch_content_from_file(const char*, void*):
../../binutils-gdb/gdb/xml-support.c:1028:43: error: ignoring return value of size_t fread(void*, size_t, size_t, FILE*), declared with attribute warn_unused_result [-Werror=unused-result]
fread (text.get (), 1, len, file.get ());
^
This commit fixes it.
