ostree: Drop tests for soup/xattr with ptest
ostree: Drop tests for soup/xattr with ptest

When ptest is enabled, both soup (for trivial-httpd) and xattr must be
enabled for all tests to pass. Rather than forcing everyone to enable
these, just document this and remove the tests since a subset of the
tests are still useful.
