build: Add feature test macros for glibc 2.19+
glibc introduced _DEFAULT_SOURCE in version 2.19 to replace _BSD_SOURCE and
_SVID_SOURCE, which were deprecated in version 2.20. Add _DEFAULT_SOURCE
where the latter two are used to be forwards-compatible and avoid warnings
about the use of deprecated definitions.
