Fixes warning on CentOS build.
Certain definitions (in this case, setgroups) need _BSD_SOURCE in
older glibc versions, but _DEFAULT_SOURCE in newer versions. The
recommended approach for compatibility across glibc versions (from
feature_test_macros(7)) is to define both.
TESTED:
Now builds without warnings on Ubuntu 14, CentOS 7, and Fedora 25.
