platform2: move --std=gnu++11 flag to common-mk/common.gypi

A number of platform2 projects enabled C++11 features individually
in their .GYP files. Removed this flag from each of the projects
and added it to common.gypi for everyone to share.

TEST=Compile various platform2 targets to make sure they still compile.
