Systemd commit [bf1b9ae487b65b1cb1639b222724fab95e508cf5](bf1b9ae487) (present in Systemd v254 and later) effectively broke gamemodelist as the process map for the `systemd --user` process became unreadable. After this change gamemodelist would exit with an error like the following:
```
awk: fatal: cannot open file `/proc/2281/maps' for reading: Permission denied
```
To work around this let's add a hook to the awk statement to skip any files that can't be read.
Closes FeralInteractive/gamemode#456
