seccomp: add arch_prctl syscall for amx

Browse Source 
When enabling amx feature, we should call arch_prctl to request
permission to use tile data for guest. The permission should be
requested before the first vcpu is created, so we need to call
arch_prctl in vmm thread. This patch adds the arch_prctl syscall for
vmm_thread_rules.

Fixes: #7516
