Fix valgrind errors in sw_tree1
The sw_tree1 testcase has accumulated some valgrind errors, at least in
the "realloc" mode.
* It had both a realloc_fdt() and explicit xmalloc() for the initial
allocation which was redundant and caused errors.
* It doesn't make sense to call fdt_resize() until after we've created
the initial stub tree
* Alignment gaps inserted into the tree contain uninitialized data, which
trips an error when we write it out. We could zero the buffer, but that
would make it easier to miss real bugs, so we add suppressions for the
valgrind warnings instead.
