urpm-package-cleanup: fix removal of the old kernels
It has been broken for a long time, may be longer than ROSA has been using nrj kernels. The tool relied on the version and release numbers of the kernel packages to find the proper ones - but these numbers have been (1, 1) for at least several years now. The relevant parts of urpm-package-cleanup have been rewritten. There are a few more notable differences compared to the old implementation: 1. The number of kernels to keep is now read from /etc/urpmi/kernels.cfg. 2. --count option is no longer supported. 3. If remove_old_kernels is set to no in /etc/urpmi/kernels.cfg, urpm-package-cleanup --oldkernels will have no effect. This may be convenient when running urpm-package-cleanup from scripts, etc. 4. The packages required by any kernel*-latest package will not be removed, so urpm-package-cleanup may keep more kernels than requested.
