    package_deb, ipk: improve subprocess output on package manager command
    
    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.
