isolation: keep CAP_SYS_PTRACE when required
When pasta is started from an existing userns and tries to join the
netns from another process it fails to open /proc/$pid/ns/net due the
missing CAP_SYS_PTRACE capability in the --netns-only case.
A simple reproducer for this.
First create a userns:
$ unshare -r
Then create a new netns inside it and try to join that netns with pasta.
$ unshare -n sleep inf &
$ pasta --config-net --netns /proc/$!/ns/net
