dummynet: Use strlcpy to appease static checkers

Browse Source 
Some dummynet modules used strcpy() to copy from a larger buffer
(dn_aqm->name) to a smaller buffer (dn_extra_parms->name).  It happens that
the lengths of the strings in the dn_aqm buffers were always hardcoded to be
smaller than the dn_extra_parms buffer ("CODEL", "PIE").

Use strlcpy() instead, to appease static checkers.  No functional change.
