Description:

The PCSX2 does not have the CAP_NET_RAW or CAP_NET_ADMIN capabilities applied to it
This is necessary for PCSX2 to fully support network enabled games

Additional info:
* package version: pcsx2 1.7.2015-1
* Relevant Log Output:
```
DEV9: Opening adapter 'eth0'...
DEV9: eth0: You don't have permission to capture on that device (socket: Operation not permitted)
DEV9: Unable to open the adapter. eth0 is not supported by pcap
Can't open Device 'eth0'
```

* Additional Note:
The command the CMAKE file uses to set the capabilities is located here https://github.com/PCSX2/pcsx2/blob/fd145e65aaa4c318d4360d2fb20b71d89376320a/pcsx2/CMakeLists.txt#L1557
It may instead need to be replicated using a script during the post-installation step.

Steps to reproduce:
Go to the Config->Network and HDD Settings
Enable Ethernet
Select either 'PCAP Switched' or 'PCAP Bridged' for the device type
Specify your adapter for 'Ethernet Device', in my case I selected 'eth0'
Apply and close the config window

Start emulation
Inspect the console for the logs (it may be easier to scroll though the logs if you pause emulation shortly after starting)

note that the log message will occur regardless of what game is booted (including the BIOS)
