rootfs.py: tweak inner warn message catching

The fix filters out irrelevant messages, and makes the catching more
accurate, the inner warn message in do_rootfs usually comes from the
output of complementary install, and pattern the format to catch it.

Here is the example of irrelevant messages:
...
|WARNING: log_check: There is a warn message in the logfile
|WARNING: log_check: Matched keyword: [warn]
|WARNING: log_check: `tmp/deploy/rpm/core2_64/pam-plugin-warn
-1.1.6-r5.0.core2_64.rpm' -> `tmp/work/intel_x86_64-wrs-linux/
wrlinux-image-installer/1.0-r0/rootfs/Packages.intel/./core2_64/
pam-plugin-warn-1.1.6-r5.0.core2_64.rpm'
...
