package/pkg-generic: depend on host-{xz, lzip} only for fitting archives

Currently, host-xz and host-lzip are built as soon as the
corresponding tools are not provided by the system, independently of
whether they are really needed by the Buildroot configuration. This is
particularly annoying for host-lzip, which is only needed for very few
packages.

This commit modifies the generic package infrastructure to only add
host-lzip and host-xz as dependencies when really needed.

[Thomas:
 - improve commit log
 - as suggested by Yann E. Morin, make the lzip case similar to the xz
   case]
