Fix unaligned load in AC-TILE MPM.

The SLOAD define using __insn_ld2s_L2 is used to provide a compiler
hint that the load will come from the L2 cache instead of the L1. It
also specifies that it is a 2 byte signed load. For the Tiny MPM, that
needs to be a 1-byte load, which is what is specified in util-ac-mpm-tile.c,
but the #undef was removing that definition.
