Think this will fix issues with the error messages generated for malformed-archives.test
in r277177 and added back this test which was deleted in r277196 while
I tracked down these problems.

Changed from constructing Twine's to std::string's as Twine's don't work

Fix the write_escaped() calls to not pass the unintended second argument
fixing the warning on the ld-x86_64-win7 bot.
