games/xracer: Call glutInit before glutCreateWindow

[iris000%duck.com@localhost]

games/xracer currently builds, but does not run.

Someone on IRC mentioned that running games/xracer fails with:

> freeglut  ERROR:  Function <glutCreateWindow> called without first
> calling 'glutInit'.

This patch adds 'glutInit (&argc, argv);' before
'program_initialization ();' so that the package is able to run again.

(TODO: Debian appears to have patches for restoring mouse pointer grab 
and building with newer GCC versions, but their patches seem invasive.)
