auto in lambda is supported from C++14, not C++11

[knorth55]

auto in lambda is introduced in #1773 . in #1773, auto in lambda is considered to enabled in c++11, but actually it is from c++14 this build error occurs in jsk_pcl_ros because jsk_pcl_ros forces to use -std=c++14 or -std=c++11, -std=c++0x. some robot with gcc, which only supports c++11 not c++14, (i.e. pr1012, fetch15) fails to build jsk_pcl_ros because of this issue.
