initcpio: Don't try to copy vendorfw to root filesystem if missing

marcan · marcan · commit 01b8d5173ba6 · 2022-12-21T18:02:11.000+09:00
This can happen on systems with broken firmware extraction/missing
upgrade to the the cpio mechanism. In this case the systems can be
temporarily fixed by unpacking the firmware to the real rootfs, but
then we shouldn't overlay it with an empty tmpfs in the initramfs.
