[PATCH container 4/8] namespaces: relax prototype of run_in_userns

[Filip Schauer <f.schauer@proxmox.com>]

Allow passing a coderef stored in a private variable as the $code
argument. This fixes the following compile-time error:

Type of arg 1 to PVE::LXC::Namespaces::run_in_userns must be block or
sub {} (not private variable) at PVE/LXC/Create.pm line 736
