[PATCH v2 1/1] generate_initramfs: fix progress reporting on dracut

["'Felix Moessbauer' via isar-users" <isar-users@googlegroups.com>]

When generating the initrd with dracut, the copy-in operations emit
output that is different from the initramfs-tools output. This patch
extends the progress parser to also support the dracut output.

Prior to the patch, the progress bar stayed at 0% until the task was
finished.
