libsoup: add patch to fix CVE-2011-2054
Fixes a security hole that caused some SoupServer users to
unintentionally allow accessing the entire local filesystem when
they thought they were only providing access to a single directory.
This is the change from libsoup-2.34.3 backported to 2.32.2. It
doesn't include the changes to the test suite though.
