[PATCH v2 2/2] lib.c: skip --param parameters

[Andy Shevchenko]

Very dumb patch to just skip --param allow-store-data-races=0 introduced in
newer GCC versions.

Without this patch sparse recognizes parameter of the --param option as a file
name which obviously couldn't be found.

The patch for easy implementation's sake slightly changed behaviour of
--version. Instead of exact keyword it will recognize anything starting with
--version as a correct option.
