instance: ujail: Fix allocated size for no_new_privs parameter

When the no_new_privs parameter is given, thei size of the  array which
contains the argv pointers is not increased in instance_jail_parse()
which causes a buffer overflow. Fix this by requesting one more entry in
instance_jail_parse() for the allocation.

Fixes: dfd5816bcbef ("instance, ujail: wire no_new_privs (-c) option")
