Have the bad breakpad symbol file unit test use garbage data.
Have the bad breakpad symbol file unit test use garbage data.

It was not possible to test garbage data before for invalid symbol
files, so we just used timestamps. Now that the generate breakpad symbol
script can inspect the symbol file we can have it check for garbage
data now instead of just using an empty file.
