Mark several getaddrinfo tests as XFAIL

These tests were recently enabled on main and have failed consistently
since they were enabled.

• lib.libc.net.getaddrinfo.getaddrinfo.basic
• lib.libc.net.getaddrinfo.getaddrinfo.nofamily
• lib.libc.net.getaddrinfo.getaddrinfo_test.basic
• lib.libc.net.getaddrinfo.getaddrinfo_test.empty_servname
• lib.libc.net.getaddrinfo.getaddrinfo_test.sock_raw

Mark them as expected failures so they no longer count as failures in
Jenkins CI.
