[Piglit] [PATCH] arb_direct_state_access: Fix Clang absolute-value warning.

getcompressedtextureimage.c:121:7: warning: using floating point absolute value function 'fabs' when argument is of integer type [-Wabsolute-value]
                if (fabs((int)data[i] - (int)expected[i]) > tolerance) {
                    ^
getcompressedtextureimage.c:121:7: note: use function 'abs' instead
                if (fabs((int)data[i] - (int)expected[i]) > tolerance) {
                    ^~~~
                    abs
