microbenchmarks: Update common.mk with symbolic and visibility flags

This syncs common.mk with the latest source in src/platform2/common-mk.
Main change that affects the compiled binary are the newly added
-fvisibility-inlines-hidden CXXFLAGS and the -Bsymbolic-non-weak
LDFLAGS (see comments in the file for what these do).
