selftests/bpf: skip BPF_PROG_TYPE_LIRC_MODE2 in libbpf_probe_prog_types
Bugzilla: https://bugzilla.redhat.com/2130850 Upstream Status: RHEL only
libbpf_probe_prog_types expects CONFIG_BPF_LIRC_MODE2 to be set, but it is not in RHEL. Skip BPF_PROG_TYPE_LIRC_MODE2 to avoid the failure.
This is RHEL-only because upstream expects selftests to work only with a specific configuration and they refuse to accept patches working around configuration issues.
