package/pkg-generic.mk: really make DL_SUBDIR inheritance work

Browse Source 
While bumping kodi, we figured out that the kodi-texturepacker and
kodi-jsonschemabuilder were both re-downloading the main Kodi tarball,
even though they contain:

KODI_JSONSCHEMABUILDER_DL_SUBDIR = kodi
KODI_TEXTUREPACKER_DL_SUBDIR = kodi

Both are host packages, and turns out that changing those variables to
HOST_ ones made the download sharing work.

Commit efa7712b09 ("package/pkg-generic:
host variant inherits target download settings") introduced
inheritance of host variables from target variables from a number of
variables, including DL_SUBDIR. But it missed the fact that earlier in
pkg-generic.mk, the following line was defined:

  $(2)_DL_SUBDIR ?= $$($(2)_RAWNAME)

So, when this later code kicked in:

 ifndef $(2)_DL_SUBDIR
  ifdef $(3)_DL_SUBDIR
   $(2)_DL_SUBDIR = $$($(3)_DL_SUBDIR)
  endif
 endif

In fact it never did anything because $(2)_DL_SUBDIR would never be
undefined. This commit fixes this issue by properly adjusting the
logic to inherit the value of the target variable when it exists, or
defaulting to $$($(2)_RAWNAME) otherwise.
