[OE-core] [PATCH 1/5] rootfs.py: two changes regarding log checking

[Chen Qi]

This patch involves two changes.

1. Extend the regular expression to also catch '^WRARNING:' in _log_check_warn.
   Warnings from bb.note or bbnote begin with 'WARNING:'. So if we decide to
   catch warnings at rootfs time, we should not ignore those produced by
   the build system itself.

2. Delay _log_check in rootfs process so that more warnings are likely to be
   catched. Note that we should at least delay the _log_check after the
   execution of ROOTFS_POSTPROCESS_COMMANDS, because we want to catch warnings
   there.
