rootless: block signals on re-exec
we are allowed to use only signal safe functions between a fork of a
multithreaded application and the next execve. Since setenv(3) is not
signal safe, block signals. We are already doing it for creating a
new namespace.
This is mostly a cleanup since reexec_in_user_namespace_wait is used
only only to join existing namespaces when we have not a pause.pid
file.
