optirun script not properly detecting 32/64 bit binaries

[de2Zotjes]

The optirun script does not find the actual file being run when one does not provide an absolute path. And even when providing an absolute path, if it is a symlink the script does not follow the symlink.

below is a diff to enable proper handling of path binaries and symlinks:

Also see issue #236 (https://github.com/MrMEEE/ironhide/issues/236 ). I wrote a slightly different solution to fix the same problem. It uses readlink to get the absolute path of symlinks. It also fixes a bug for detecting whether wine is being executed.
