package/expat: security bump to version 2.5.0

Expat 2.5.0 has been released earlier today. Most importantly, this
release fixes CVE-2022-43680: a heap use-after-free vulnerability after
overeager destruction of a shared DTD in function
XML_ExternalEntityParserCreate in out-of-memory situations, with
expected impact of denial of service or potentially arbitrary code
execution.
