initramfs: avoid copying non-microcode data into the early-initramfs
Ensure only microcode_amd*.bin files will be concatenated into the
early-initramfs microcode data file. Otherwise, non-microcode data
files that happen to be present in the firmware source directory will
corrupt the data stream, and the kernel will most likely fail to find
the desired microcode update in the resulting mess.
While this doesn't happen when using *only* microcode data from
unmodified Debian packages, it will happen should the full contents of
the amd-ucode/ directory from upstream linux-firmware (which contains a
README and some .asc gnupg signature files) be used as the source of the
microcode data.
Thanks to Eric Valette for reporting the issue, tracking down the root
cause, and suggesting a fix.
