    selftests/sched_ext: Add -fms-extensions to bpf build flags

    Similar to commit 835a50753579 ("selftests/bpf: Add -fms-extensions to
    bpf build flags") and commit 639f58a0f480 ("bpftool: Fix build warnings
    due to MS extensions")

    Fix "declaration does not declare anything" warning by using
    -fms-extensions and -Wno-microsoft-anon-tag flags to build bpf programs
    that #include "vmlinux.h"
