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*`. 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.
