[Buildroot] [PATCH 2/8] infra/pkg-generic: don't set INSTALL_{TARGET, STAGING, IMAGES} for host

[Yann E. MORIN]

By their very nature, host packages have no target, staging, or
images install steps; they have a single install step, that is
always performed.

As sucj, setting the corresponding _INSTALL_{TARGET,STAGING,IMAGES}
variables does not make sense for host packages.

However, people (and scripts) may get confused when they process the
output of printvars, e.g.:

    $ make printvars VARS=HOST_LIBTOOL_INSTALL_TARGET
    HOST_LIBTOOL_INSTALL_TARGET=YES

Only set those variables for target packages. There is no corresponding
variable for host packages, as they are always installed (and only
once).
