[7.16](backport #28117) Allow clone3 syscall in seccomp filters (#28330)

* seccomp: allow clone3 syscall for x86 (#28117) clone3 is a linux syscall that is now used by glibc starting version 2.34. It is used when pthread_create() gets called. Current seccomp filters do not allow this syscall leading to crashes like runtime/cgo: pthread_create failed: Operation not permitted See elastic/apm-server#6238 for more details (cherry picked from commit 82507fd) Co-authored-by: Arnaud Lefebvre <[email protected]> Co-authored-by: Jaime Soriano Pastor <[email protected]>
