[OE-core] [PATCH 1/1] package_ipk.bbclass: Replace empty lines in DESCRIPTION with '.'

[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 replace empty lines in DESCRIPTION with a '.' when generating
an ipk package to avoid this issue.
