sysctl: Set fs.suid_dumpable=2 for release builds

This commit enables dumping all processes - including those considered
by kernel as "suid".

Process is considered "suid" not only when it does (among other)
setuid/setgid but also when Capabilities are defined in systemd
unit.  With suid_dumpable=0 crash of such "suid" processes would
not trigger execution of crash-worker by the kernel.

Please see suid_dumpable description in proc(5) for full explanation
what kernel considers "suid".
