package/pkg-generic: handle host-fakedate as a regular dependency

This commit moves the host-fakedate dependency handling from
DEPENDENCIES_HOST_PREREQ to a proper regular dependency handled by the
package infrastructure.

host-fakedate is added as dependency to all packages, except
host-skeleton, because we depend on it.

In addition, we make sure that host-fakedate does not grow a
dependency on host-{tar,xz,lzip,ccache} to avoid circular
dependencies. host-fakedate does not need any extraction tool and does
not need to build C/C++ code (the source code is just a shell script
available in Buildroot).
