Fail with a proper error message if input file is not found.

Browse source 
Previously, if the input file was missing, the symupload tool on Mac
would happily process, try to parse it (calling a method on nil) and
fail when trying to create the payload to send to the server as one
of the method raised a NSInvalidArgumentException when receiving a
nil value.

Change to code to instead check the file for existence which makes it
easier to understand what is happening when part of the build system
is misconfigured and invoke symupload without first creating the symbol
file.
