[OE-core] [PATCH 1/2] package_deb, ipk: improve subprocess output on package manager command

[leonardo.sandoval.gonzalez at linux.intel.com]

From: Leonardo Sandoval <leonardo.sandoval.gonzalez at linux.intel.com>

Redirecting stderr to stdout helps debugging issues, i.e instead of just
getting the return code, get also the error log from the pkg manger
This commit is in the way to figure out the root cause of [YOCTO #12012],
where dpkg-deb fails with a 2 return code and according to the man page,
there are multiple issues leading to the same code.
