log-tree: use FLEX_ARRAY in name_decoration
We are already using the flex-array technique; let's
annotate it with our usual FLEX_ARRAY macro. Besides being
more readable, this is slightly more efficient on compilers
that understand flex-arrays.
Note that we need to bump the allocation in add_name_decoration,
which did not explicitly add one byte for the NUL terminator
of the string we are putting into the flex-array (it did not
need to before, because the struct itself was over-allocated
by one byte).
