[testsuite] fix loop index for gcc.dg/webizer.c

[Janis Johnson]

Execution of test gcc.dg/webizer.c fails with a segfault for
powerpc-eabi with the GNU simulator.  The test has an array of size 2
and accesses that array with indices of 1 and 2.  This patch fixes the
bounds of the loop index.

Tested on powerpc-none-eabi; OK for trunk?
