Subject: [PATCH] plpython: Fix sed expression in python3 build

The old expression sed 's,$(srcdir),python3,' would normally resolve
as sed 's,.,python3,', which is not really what we wanted.  While it
doesn't actually break anything right now, it's still wrong, so put in
a bit more work to make it more robust.
