[OE-core] [PATCH 1/1] package_ipk.bbclass: Add check for empty lines in DESCRIPTION

[mariano.lopez at linux.intel.com]

From: Mariano Lopez <mariano.lopez at linux.intel.com>

opkg uses empty lines as separator for next package and if an ipk
file was packaged with empty lines in DESCRIPTION opkg won't be
able to handle such ipk file, this happens at execution time.

This commit will add a check for empty lines in DESCRIPTION when
generating to ipk package to avoid this issue.
