dhcp 3.0.5 was causing build issues due to its build system not based
on the autotools. Instead of work-arounding dhcp 3.0.5 issues, this
commit bumps to 4.1.1 which uses the autotools as the build
system. The package is therefore converted to the autotools
infrastructure.
The dhcp_xecute patch is no longer needed, this feature seems to have
been merged into the upstream dhcp (according to the manpage).
