Subject: [PATCH] fix(autoconfigure): only pair kernels with an initramfs that
 is a file

The initramfs candidates were checked with try_exists, which also
accepts a directory, and fails the whole scan on any error other than
the file not being found. Only accept a regular file, and treat a
candidate that can't be checked as missing.
