make 17 state-changing execing applets (ex: "nice PROG ARGS") noexec
The applets with "<applet> [opts] PROG ARGS" API very quickly exec
another program, noexec is okay for them:
chpst/envdir/envuidgid/softlimit/setuidgid
chroot
chrt
ionice
nice
nohup
setarch/linux32/linux64
taskset
cttyhack
"reset" and "sulogin" applets don't have this form, but also exec
another program at once, thus made noexec too.
