trafgen: parser: Check read access to file before invoking cpp
If a non-accessible (or non-existing) file is passed to trafgen and the
-p/--cpp option is used, the preprocessor will fail but trafgen will
continue running and producing follow-up errors messages:
cpp: error: foo.conf: No such file or directory
cpp: warning: ‘-x c’ after last input file has no effect
cpp: fatal error: no input files
compilation terminated.

To avoid this, check that the file is readable before passing it to the
preprocessor and error out if is not readable.
