test-http: use sed instead of fixed-with cut for reading access.log

Some systems (like FreeBSD jails) use something other than 127.0.0.1
for localhost, and it's not safe to assume it'll always be the same
width. Using sed with a replacement like this sidesteps the problem.

  $ hg init

  $ echo 123 > a
  $ hg add a
  $ hg commit -m "first" a

  $ mkdir sub
  $ echo 321 > sub/b
  $ hg add sub/b
  $ hg commit -m "second" sub/b

  $ cat sub/b
  321

  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ cat sub/b 2>/dev/null || echo "sub/b not present"
  sub/b not present

  $ test -d sub || echo "sub not present"
  sub not present
