Update code to test whether zip can run in the target system before adding it to PATH.

zip binary was causing either a "segmentation fault" or a "kernel too old" in some specific systems making the output file creation to fail.

Fix tclahr#245
Add verbose message.
Bind mounts can be used to hide processes (see https://dfir.ch/posts/slash-proc/). One of the quickest ways to detect this behavior is to "grep /proc /proc/self/mounts". Because /proc/*/mounts are not necessarily the same across all processes, collect all of them.
