Subzero: switch from llvm-objdump to objdump for lit tests (for LLVM merge)

tests_lit/lit.cfg

 # -*- Python -*-
 # Taken from utils/lit/tests in the LLVM tree and hacked together to support
 # our tests.
 #
 # Note: This configuration has simple commands to run Subzero's translator.
 # They have the form %X2i (i.e. %p2i, %l2i, and %lc2i) where X is defined
 # as follows:
 #
 #   p : Run Subzero's translator, building ICE from PNaCl bitcode directly.
 #   l : Run Subzero's translator, converting the .ll file to a PNaCl bitcode
