[PATCH 3/8] lib-rebase: loosen GETTEXT_POISON check in fake editor

The fake editor script created by 't/lib-rebase.sh' recognizes GETTEXT
POSION output when the first line of the file to be edited consists
solely of the GETTEXT POISON magic string as a comment.  However, a
later patch will include additional text after that magic string, so
that check won't work anymore.

So instead of expecting an exact match in the first line, check
whether there are any lines starting with the commented out magic
string.
