[OE-core] [PATCH 1/1] insane.bbclass: maybe no log.do_compile or log.do_install

[Robert Yang]

The insane.bbclass grep in log.do_compile and log.do_install
unconditionally, but there maybe no such logs when mirror the pkg from
sstate cache file. We should check whether the log file exists or not
before grep in it.

Additionally, break the one too long line into two (Add a "\n").
