This makes t/no-tabs.t pass.
I'm responsible for some tabs in previous patches, so this
fixes mine also :)
Note that I find this test silly, but "dura lex, sed lex"...
70-install-ssh: "ssh" package doesn't fully resolve on atleast the newer distros, changed the package "ssh" to "openssh-server"
80-install-kernel: new script to install a kernel for the pygrub flag
80-install-modules: added support for pygrub, this script is essentially ignored if pygrub is set. The kernel script will install modules in that case.
