#3116: Enable CXX11 ABI

Summary:
We use a `-D_GLIBCXX_USE_CXX11_ABI=0` build option which we actually don't need and this causes single-line `std::string::_Rep::_S_create` stack traces in heap profiles which are responsible for a high amount of memory consumption in some of the scenarios we've seen investigating OOM issues.

This change removes this option from both YB and third-party builds, so we will be using correct `std::string` implementation instead of the old one for GCC builds.

Test Plan:
- Jenkins
- Populated cluster with data using `java -jar ~/code/yb-sample-apps.jar --workload CassandraBatchTimeseries --nodes $NODES --num_writes 100000 --num_threads_read 1 --num_threads_write 4 --min_metrics_count 10000 --max_metrics_count 20000 --num_unique_keys 1000000000 --nouuid --value_size 100`. Performed rolling upgrade. Checked that data is kept and there are no backward compatibility errors.
- Checked local RF=3 cluster on AWS m3.xlarge with Xeon E5-2665. Tried load and query ysql sample data.
