funman300 7dbd878398 test: update mutation-battery anchors after rustfmt reflow
Formatting reflowed two mutation target lines onto multiple lines; update
the battery anchors (adapter #14 kit lookup, host #19 Content-Length push)
to the new unique substrings. Both batteries kill all mutants again
(adapter 14/14, host 20/20).

# FIFA 17 squad HOST mutation battery.
#
# Each mutation injects a specific wrong behaviour into the committed source
# (host, or the adapter it composes), runs the ONE host test that defends the
# invariant, and requires that test to FAIL (mutant killed). Source is reverted
# via `git checkout` after every mutation. A SURVIVOR fails the battery.
#
# Run from the host crate root: bash mutation-battery.sh
