[roll] Roll fuchsia [netstack3] Fix reassembly of IP fragments

Fix a bug in the reassembly of out-of-order IP fragments. This original
code was incorrectly computing the gaps between fragments, only when 1)
the current fragment fills a gap *before* an existing fragment (i.e. an
out-of-order fragment) and 2) when the current fragment's size is
greater than `FRAGMENT_BLOCK_SIZE`.

The fix itself is trivial; the majority of this diff in this CL is to
update the tests to support testing reassembly on fragments of different
sizes. The original test coverage only exercised fragments with
`FRAGMENT_BLOCK_SIZE`, which kept this bug hidden.
