Please accept this patch to recursively include theme files in dracut

[Michael Goodwin]

Hi, 

I'm submitting this patch because I have encountered problems with dracut 
being able to include anything but flat themes. Some themes such as "plymouth-
theme-breeze" contain directories with images (in this case ./images) and I 
believe the script scripts/plymouth-populate-initrd.in should handle this 
better, as well as the dracut-only script `modules.d/50plymouth/plymouth-
populate-initrd.sh` for which I will be contacting that project separately.

I'm pasting the patch inline below for reading, and including it as a file for 
your convenience.

Thanks,

Mike

Subject: [PATCH 1/1] scripts: Add inst_recur for adding themes recursively

Some themes are configured and shipped with directories and aren't flat
this patch solves that by writing a pure bash function to recurse over
those directories and files in order to include every bit of the theme
into the initramfs.

Without this, users typically experience a black screen at boot time and
don't understand why their theme doesn't function:

A similar funciton and patch will be filed for the dracut-only
component: `modules.d/50plymouth/plymouth-populate-initrd.sh`
