[OE-core] [PATCH 2/2] package: Fix various rpmdeps relocation issues

[Richard Purdie]

There are several issues with rpmdeps after the rpm v5 -> v4 transition:
 * _rpmfc_magic_path  is an invalid option for rpm4
 * --rpmpopt is an invalid option for rpm4
 * we need to use the path to rpmrc since otherwise it poitns at the
   original build path
 * we need to set MAGIC in the environment so libmagic can find its
   files.

This patch addresses those and ensures rpmdeps works in relocated builds
from sstate (or with rm_work).
