Increase memory to 512M for freebsd template

[tzsz0]

Hello,

I was just doing a fresh install of freebsd inside a vm (host also freebsd) and noticed that the install did not complete successfully. The installer always crashed while installing the base system via pkg (I'm using the pkgbase path) and could not install the system after multiple attempts.

Increasing the memory for the VM resolved the issue and the vm got installed on the first attempt.

I assume the pkgbase install has a bit more resource requirements than the traditional set way, so it'd probably be appropriate to increase the default value here accordingly. I can also hardly imagine any scenario where 256M is a hard limit for anyone doing virtualization.

Additionally, some other templates like ubuntu are only requesting 512M as of now while the official documentation from Canonical states, that 1G (or 1.5G for ISO) is the minimum.

@bapt Can you confirm that pkg for pkgbase requires now more memory?

What I can confirm, is that the more package we get the more memory it taks while computing upgrades, and yes right now, I failed at getting below 256M with pkgbase, but it is still in my TODO to allow it again.
