generic/228 changes kernel.core_pattern, so it saves it beforehand in
order to restore it. However, it adds an extra space in the process:
$ echo \"$(sysctl kernel.core_pattern | awk -F = '{print $NF}')\"
" |/usr/lib/systemd/systemd-coredump %P %u %g %s %t %c %h %e"
Instead of using awk, just use sysctl -n to only print the value.
