tests: fix portability of sed usage in test-mq

on some platform (Mac OS X and Solaris, at least), to insert new text
line, sed function 'i' should be followed by:

  - backslash('\'),
  - new-line,
  - text to be inserted and
  - new-line

GNU sed on Linux can recognize both previous and new ones as same
modification request.

in addition to it, this patch avoids to use '-i' option for sed,
because it is not so portable, as noted in WritingTests wiki page.

  $ hg init
  $ echo a > a
  $ hg add a
  $ hg commit -m test

Do we ever miss a sub-second change?:

  $ for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20; do
  >     hg co -qC 0
  >     echo b > a
  >     hg st
  > done
