genkernel patch

Hi, attached is a patch to address an issue I ran into copying explicit firmware files into initramfs with FIRMWARE_FILES = "{file1},{file2},{file3}" in genkernel.conf,

The kernel is looking for some firmware files in subfolders of the /lib/firmware dir, this patch copies the firmware files into their subfolders if needed so the kernel finds them properly on load.

This was solved via https://gitweb.gentoo.org/proj/genkernel.git/commit/?id=c576f99b0bbdb2c938d5b73eee61d876ef7cca88

Just verified, calling `genkernel --firmware-files="ath6k 3com" initramfs` will produce an initramfs containing 3com and ath6k folder from --firmware-dir. Folder structure was preserved:
