postmarketos: implement is_kernel_package

There are many many kernel packages in pmOS+Alpine and the pkg names
don't follow any specific pattern that sets them apart from some other
non-kernel packages, so the implementation tries to exclude known
pkgs that are not kernels and assume anything that doesn't match these
package names/patterns are kernel packages.
