Bug#1063155: needrestart: fails to recognize versioned ruby interpreters

[Helmut Grohne]

Package: needrestart
Version: 3.6-4
Tags: patch upstream

Hi,

I noticed that needrestart wouldn't reliably restart debci. Looking
deeper I noticed that a missing process was a Ruby process. Its $bin was
resolved as "/usr/bin/ruby3.1". If you look at the isa sub in
Interp/Ruby.pm, you see that it'll reject this as a Ruby process due to
the version. Hence, the process is ignored and not restarted. I'm
attaching a patch that extends the process pattern to allow a versioned
interpreter.
