[PATCH 13/14] xfree86/os-support: Mark some variables as unused.

[Cyril Brulebois]

Keep on setting them (since the strtok() calls have side-effects), but
mark them as unused, since they aren't used afterwards (except in dead
code which should probably go away).

Those warnings go away accordingly:
|   CC     lnx_acpi.lo
| lnx_acpi.c: In function 'lnxACPIGetEventFromOs':
| lnx_acpi.c:78:8: warning: variable 'GFX' set but not used [-Wunused-but-set-variable]
| lnx_acpi.c:77:8: warning: variable 'video' set but not used [-Wunused-but-set-variable]
