[libFuzzer] Increase the iteration limit in shrink.test
After https://reviews.llvm.org/D48800, shrink.test started failing on
x86_64h architecture.
Looking into this, the optimization pass is too eager to unroll the loop
on x86_64h, possibly leading to worse coverage data.
Alternative solutions include not unrolling the loop when fuzzing, or
disabling this test on that architecture.
