Manual pages: nsenter.1: clarify the intro discussion

The intro paragraph talks about entering the namespace of other
processes. That's not quite accurate, since nsenter can be used (via
a bind mount) to enter a namespace that has no member processes.  So
rework NAME and the intro paragraph in DESCRIPTION to remove mention
of "processes".
