compat-util: add _DEFAULT_SOURCE define
glibc has deprecated the use of _BSD_SOURCE define
warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE"
To make it easier to maintain a cross platform source code, that
warning can be suppressed by _DEFAULT_SOURCE.
Define both _BSD_SOURCE and _DEFAULT_SOURCE to clean-up the build.
