this is the "ptrace" equivalent for applications that use user
namespaces like, i think, firefox and flatpak. This event will surface
if you do a `ps auxZ` when you have a running instance of a application
the uses user name spaces.

In the case of firefox you would for example append it below this line:
https://github.com/SELinuxProject/refpolicy/blob/master/policy/modules/apps/mozilla.if#L40
like so:
allow $2 mozilla_t:cap_userns sys_ptrace;
