TT#19158 Make check on debianrepo + sipwiserepo boot options more explicit

checkBootParam triggers on boot option 'debianrepo' if boot
option 'debianrepotransport' is set, same applies to 'sipwiserepo'
vs 'sipwiserepotransport'.

So be more specific about those checkBootParam checks,
without having to modify the existing behavior of
checkBootParam internals.
