cmd/venti/srv: split memory allocation call
This splits a certain vtmallocz call in mkihash into two vtmallocz
calls. The first issue this fixes is that the C aliasing rules were not
respected in the code before this commit. The other thing is that this
enables better memory alignment guarantees.
Updates #313
