Subject: [PATCH] libtests/cxx11.cc: fix build with gcc 4.8

Build fails on gcc 4.8 since version 9.1.1 and commit
752416554086d5d34323bc14164d5084db83cfbd:

libtests/cxx11.cc: In function 'void do_regex()':
libtests/cxx11.cc:347:42: error: 'strlen' is not a member of 'std'
     std::cregex_iterator m3(str7, str7 + std::strlen(str7), expr4);
                                          ^

To fix the build failure, add missing include on cstring
