Subject: fix(test): bump default VM RAM to 8 GiB to stop AUR-build OOM kills

The zfs green run OOM-killed cc1plus three times during AUR C++ builds:
makepkg runs -j$VM_CPUS (4), and parallel compiles at ~700 MB each overran
the 4 GiB default. The install still passed (yay retries), but the kills
showed up as attributed issues. 8 GiB gives the four jobs headroom.
Overridable via VM_RAM as before.
