Subject: [PATCH] Use delete action for clean up *.pyc files

Findutils added in release 4.2.3 a new --delete action for deleting
matching files. This action performs better than -exec rm {} \;
because it doesn't have to spawn an external process.  This change
uses a new action whenever is possible.
