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 repo
  $ cd repo

  $ echo line 1 > foo
  $ hg ci -qAm 'add foo'

copy foo to bar and change both files
  $ hg cp foo bar
  $ echo line 2-1 >> foo
  $ echo line 2-2 >> bar
  $ hg ci -m 'cp foo bar; change both'

in another branch, change foo in a way that doesn't conflict with
the other changes
  $ hg up -qC 0
  $ echo line 0 > foo
  $ hg cat foo >> foo
  $ hg ci -m 'change foo'
  created new head

we get conflicts that shouldn't be there
