Fix GH-22138: skip libxml/xmlreader tests on non-ASCII paths.

libxml2 2.13+ rejects unencoded non-ASCII bytes in SYSTEM URIs via
xmlBuildURISafe and emits "Can't resolve URI", which breaks four tests
when the source tree lives under a path like "~/下载/". Skip them with
a clear reason on such paths, and loosen the EXPECTF for the two tests
that previously matched only "failed to load" so both libxml2 message
formats are accepted.

close GH-22150
