net-tools: Update to 2.10

- Update net-tools from 1.60 to 2.10
- Based on guidance from Michael Tremer
	- new no-hostname patch created to remove all hostname references
		from makefile
	- all other patch files removed from lfs as no longer needed
- version 2.10 places ifconfig and route tools in bin instead of sbin
	those tools moved to sbin to keep in line with previous approach
- make update replaced by make install as there is no longer a make
	rule for make update
- Updated rootfiles
