[PATCH] package_manager/ipk: do not pipe stderr to stdout

Shruthi Ravichandran

When parsing the output of a command, do not pipe stderr to stdout.
Opkg sometimes prints harmless error messages even when the opkg
command succeeds. When stderr is piped to stdout, these error
messages may clobber the stdout and cause unexpected results while
parsing the output.
