tools headers UAPI: Sync unistd.h to pick {list,stat}mount, lsm_{[gs]et_self_attr,list_modules} syscall numbers

To pick the changes in these csets:

d8b0f5465012538c ("wire up syscalls for statmount/listmount")
5f42375904b08890 ("LSM: wireup Linux Security Module syscalls")

Used in some architectures to create syscall tables.

This addresses this perf build warning:
