Bug#202719: start-stop-daemon: --exec should also check the first argument of /proc/PID/cmdline

[Tobias Burnus <tobias.burnus@physik.fu-berlin.de>]

Package: dpkg
Version: 1.9.21
Severity: normal

Currently, start-stop-daemon only checks the /proc/PID/exe if started
with the --exex|-e option. The problem is: If a program is e.g. a PERL
script, /proc/PID/exe -> /usr/bin/perl. Therefore the /proc/PID/cmdline
is of interest.

This is needed because of Debian bug:
  #167757: lsb: start_daemon start already running programs
