bootconfig: skip internal tree sanity checks in kernel

In xbc_verify_tree(), the loop iterating through all nodes to check that
xbc_nodes[i].next < xbc_node_num and xbc_nodes[i].child < xbc_node_num is
a defensive sanity check against implementation regressions (such an
out-of-bounds index cannot be produced by malformed input).

Running this check in the kernel adds unnecessary boot-time overhead. 
Split this check out into xbc_sanity_check_tree() for userspace, so that
it continues to run during userspace bootconfig validation (e.g.  when
applying or testing bootconfig with tools/bootconfig), but is omitted in
the kernel to speed up initialization.
