samples/landlock: Fix building on musl libc
Building with make allyesconfig on musl results in the following
In file included from samples/landlock/sandboxer.c:22:
/usr/include/sys/prctl.h:88:8: error: redefinition of 'struct prctl_mm_map'
88 | struct prctl_mm_map {
| ^~~~~~~~~~~~
In file included from samples/landlock/sandboxer.c:16:
usr/include/linux/prctl.h:134:8: note: originally defined here
134 | struct prctl_mm_map {
| ^~~~~~~~~~~~
This is mainly due to difference in the sys/prctl.h between glibc and
musl. The struct prctl_mm_map is defined in sys/prctl.h in musl.
