kernel-install: teach bot loader spec entry generator to generate entries with "tries"
This makes two changes:
1. When called for "remove" any drop-ins with "+" suffix are removed
too, so that the logic works for entries with boot counting enabled
too and we don't lose track of configuration snippets created that
way.
2. When called for "add" we optionally generate a "+" suffix, based on
the data in /etc/kernel/tries if it exists.
This basically means after "echo 5 > /etc/kernel/tries" any installed
kernels will automatically set up for 5 boot tries before older
kernels will be tried.
