cinap_lenrek 03f364d167 inst/ndbsetup: allow setting sysname more than once
In the installation, if you run the ndbsetup task n times (n > 1),
the installed /lib/ndb/local will have n sys= entries.

The problem is that ndb(8) will use the first sys= entry found, but
one would expect that the last configuration in the ndbsetup task
would be the active one.

Remove any previous entry in ndbsetup before adding new one.
