This isn't the easiest of starting points for a mask, but it can be
done by using `r.clump'. This will create three data clumps (one
consisting of the original 1's, the other two of the 0's inside and
the 0's outside). Then you can run `r.mask' to decide which of these
clumps you want to use as a mask...
