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.
