ARM: 8802/1: Call syscall_trace_exit even when system call skipped
[ Upstream commit f18aef742c8fbd68e280dff0a63ba0ca6ee8ad85 ]
On at least x86 and ARM64, and as documented in the ptrace man page
a skipped system call will still cause a syscall exit ptrace stop.
Previous to this commit 32-bit ARM did not, resulting in strace
being confused when seccomp skips system calls.
This change also impacts programs that use ptrace to skip system calls.
