Bug#630197: prevent migration

[Robert Millan]

found 630197 1.99-7
notfound 630197 1.99-6
retitle 630197 grub 1.99-7 is linked with libgeom0 8.2, but testing
has libgeom0 8.1
thanks

1.99-7 has just been uploaded and was linked with libgeom 8.2 [1][2].

This is much better than being linked with 8.1 in a suite
where it can only be used with 8.2 (leads to segfault and unbootable
system).

Now we need to prevent migration which would cause the opposite
situation: grub linked with 8.2 being used with 8.1 in wheezy.  This
bug should that from happening.

An alternative would be adjusting shlibs.local as proposed by
Jonathan to make grub depend on libgeom0 >= 8.2, but given
that it's only a temporary solution (untill next libgeom upload) I'm
not sure it's worth the hassle.
