[Bug translator/5897] New: derived_probe derivation chain tweak

["fche at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

In an area recently worked on in bug #5609, an additional
improvement would be nice.  For

% stap -p2 -v -e 'probe syscall.r* {}'

we get

kernel.function("compat_sys_rt_sigtimedwait@kernel/compat.c:777")? /* pc=0x5b38a
*/ /* <-
kernel.function("sys_rt_sigtimedwait"),kernel.function("compat_sys_rt_sigtimedwait")?
<- syscall.r* */

The derivation chain printed in the /* comment */ misses the individual
syscall.read or whatnot that matched the initial "syscall.r*" pattern.
It should be listed there.
