various profile fixes (#1433)

* calibre: add netlink protocol (FB note: removed before merge)

calibre started without netlink protocol throws following error in console:

Exception in thread Thread-8:
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 801, in __bootstrap_inner
    self.run()
  File "/usr/lib/calibre/calibre/utils/mdns.py", line 43, in run
    _all_ip_addresses = self.get_all_ips()
  File "/usr/lib/calibre/calibre/utils/mdns.py", line 27, in get_all_ips
    for x in netifaces.interfaces():
OSError: [Errno 95] Operation not supported

* mpv: add nogroups, tracelog, ipc-namespace, private-dev

I used testes all above options and didn't noticed any breakage.

* qbittorrent: add netlink protocol, private-etc

Netlink protocol is needed if user select to bind specific network interface in config. Otherwise it throws an error in qbittorent log:
The network interface defined is invalid: tun0

Example private-etc is added but commented out by default. It's tested but as there are many different system configurations users should enable it manually.

* vlc: disable memory-deny-write-execute

With memory-deny-write-execute vlc freezes after loading video file. According to https://github.com/VladimirSchowalter20/firejail/commit/b18f42ab0236de7eed5888f43ba36cdaf990cbca memory-deny-write-execute is similar to PAX mprotect feature and linked github project explicitly disables that feature for vlc binary, see https://github.com/copperhead/paxd-archive/commit/deb39e0b91996e2e9c7917b3543030880cd476f4

* Update vlc.profile

* wine: add nogroups

Nogroups should be safe addition for wine

* wireshark: allow users to run wireshark as non-root

Wireshark can be run unprivileged when user is part of wireshark group. Unfortunately enabling nogroups,nonewprivs and seccomp will break it with permissions errors.

Also added example private-etc option which is commented out by default for now.

* cosmetic fix

* mpv: comment out ipc-namespace for now

As requested in review https://github.com/netblue30/firejail/pull/1433#discussion_r131550515

* calibre: disable netlink protocol

It throws an error but actual breakage isn't observed for now.
