I looked for kernels in /boot and modules in /lib/modules.

We don't need '|| true' if you do not refer to non-existent files.
I included both dirs as libguestfs checks both of them. If that doesn't
convince you, I can send a v3 with just `chmod +r /boot/vmlinu*`.
We are on Ubuntu. We only need to consider files that Ubuntu actually
provides.

I actually misread the error message above as mentioning both dirs for
kernel so I didn't explicitly write it in the commit message, but the
source code [1] confirms that both are checked.
