reloc: silence warning from readelf

Browse Source 
we've been seeing errors like

```
10:39:36  gdb-add-index: [Was there no debuginfo? Was there already an index?]
10:39:36  readelf: /jenkins/workspace/scylla-master/next/scylla/build/dist/debug/redhat/BUILDROOT/scylla-5.3.0~dev-0.20230321.0f97d464d32b.x86_64/usr/lib/debug/opt/scylladb/libreloc/libc.so.6-5.3.0~dev-0.20230321.0f97d464d32b.x86_64.debug: Error: Unable to find program interpreter name
```

when strip.sh is processing *.debug elf images. this is caused by a
known issue, see
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1012107 . and this
error is not fatal. but it is very distracting when we are trying to
find errors in jenkins logging messages.

so, in this change, the stderr output from readelf is muted for higher
signal-noise ratio in the build logging message.
