Don't specify the `-std` flag in Makefile or re2.pc.

As Frank Heckenbach notes in https://bugs.debian.org/1003482:

> re2.pc contains "-std=c++11". This conflicts with other "-std"

As gcc and clang default to C++ standards greater than 11, these days,
we can use with the default, rather than the older standard.

Fixes #352.
