osbuilder: Fix rootfs-builder when running in VMs

Browse Source 
The script runs apt sync at some point which scans all possible fds
in order to close them. The operation is incredibly slow on VMs
and may lead to build timeouts.

Fix it by limiting the container runtime fds to a sane limit.

Fixes: #2510
