When using rpm as package manager and trying to install a file called
'/usr/share/doc/What to when an Error occurs.txt'
log_check falsely errors out on the build, because used regex match on
'DEBUG: Removing manifest: /path/usr/share/doc/What
to when an Error occurs.txt'.
To handle such cases introduce IMAGE_LOG_CHECK_EXCLUDES, to allow
user to add custom exclude regex to log_check exclude list
