When a program is a link to an executable, and this executable is
handled by update-alternatives, renamed to a different name, cmd
`pidof full_path_of_program` will not work.
Eg:
/usr/sbin/httpd -> /usr/sbin/httpd.apache2
`pidof /usr/sbin/httpd` cannot get pid of the process httpd
Backport the patch to fix above issue.
