Saleem Abdulrasool 67635a7f8d tools: address possible non-null terminated filenames ...

If a filename is a multiple of 18 characters, there will be no null-terminator.
This will result in an invalid access by the constructed StringRef.  Add a test
case to exercise this and fix that handling.  Address this same vulnerability in
llvm-readobj as well.
