Arch Linux Kerberos config causes xfreerdp to launch slowly

[takase1121]

I was having issues with WinBoat and WinApps. FreeRDP starts in the background but actually connects to Windows after 30-50 seconds, with mention of NLA negotiation issues.

This is related to FreeRDP/FreeRDP#10138 where Arch Linux ships an actual KRB config that points to a MIT server. This makes FreeRDP contact the KRB server when connecting to the VM. This fails after a timeout, which causes the delay.

There are two ways to fix this issue:

1. Use /sec:nla /auth-pkg-list:'!kerberos' to disable KRB. This did not work for me.
2. Replace /etc/krb5.conf with a dummy one:

   [libdefaults]
            default_realm = LOCALHOST

3. Use Flatpak FreeRDP. However, WinBoat does not allow you to override which FreeRDP to use and if you have FreeRDP installed via your package manager (and is depended by WinBoat), it cannot be uninstalled.

I just want to leave this here in case anyone faced the same hair-pulling issue as me.
