[Buildroot] [PATCH v3] package/pkg-utils.mk: add dl_dir to show-info output

It can be useful for scripts to be able to access a package's source
file after download. That used to be easy, just DL_DIR/PKG_SOURCE.
However, with the subdirectories in DL_DIR which can be overridden with
PKG_DL_SUBDIR, that is no longer easy.

Therefore, this patch adds dl_dir to the package information. It prints
just PKG_DL_SUBDIR, to avoid dumping absolute paths to the buildroot
directory in the show-info output.

It can be used with the following jq script to get a newline-separated
list of all downloaded files:

make show-info | jq -r '.[] | ("dl/" + .dl_dir + "/" + .downloads[]?.source)'

v2 -> v3:
 - Remove accidental change

v1 -> v2:
 - Use DL_SUBDIR (i.e. relative path) instead of DL_DIR (i.e. absolute
   path). (Yann)
 - Move the definition one level higher, because it is anyway the same
   for all sources. (Yann)
 - Update jq script in commit message to handle the above.
