net/net-snmp patch to remove PERL and headers

["Brian A. Seklecki" <lavalamp%spiritual-machines.org@localhost>]

This patch to Makefile removes the (presently) non-optional dependency on
Perl, as well removes a voluminous amount of headers from the binary
package PLIST.  Man pages are next.

Useful for embedded environments, for which, a separate discussion about
pkgsrc binary pruning is beyond the scope of this forum.

Be sure to:
  $ sudo make -k page
