some etc fixes

. split user-editable and system-owned files in etc/Makefile
	. mtab is a symlink, not a file now; remove it
	. force-install of certain system-controlled /etc files from
	  top Makefile
	. rename /etc/make.conf to /etc/mk.conf; and don't set $ARCH;
	  reduce difference in bsd.own.mk
