[Mesa-stable] [PATCH 1/2] r300g: Use PATH_MAX instead of limiting ourselves to 100 chars.

[Matt Turner]

When built with Gentoo's package manager, the Mesa source directory
exists seven directories deep. The path to the .test file is too long
and is silently truncated, leading to a crash. Just use PATH_MAX.
