package_ipk: Remove spurious '-i' in grep command for log_check

ipk_log_check uses a case-sensitive grep (which is correct) when deciding
whether there were any errors or not.  But if it decides that there were, it
then uses a case-insensitive grep to display them.  This results in a large
amount of irrelevant and confusing output which makes it hard to see the real
errors amongst the noise.

Suppress this by removing the unwanted -i.
