Subject: [PATCH] 51-dracut-rescue.install: fix initramfs not generated in
 /boot case

Commit 5e574046e76e ("5?-dracut*.install: Allow scripts to install
the initramfs in /boot dir") added support to generate initramfs
images in the /boot directory and copy the respective BLS files.

Unfortunately, it broke the rescue initramfs generation when it's
not installed on /boot due not checking for the correct condition.

It checks for the 0-rescue sub-dir to exist, but this is created so
instead if the parent sub-dir exists has to be checked. Also, check
if the destination directory is /boot or not, instead if it exists.
