selftests: centralize -D_GNU_SOURCE= to CFLAGS in lib.mk
Centralize the _GNU_SOURCE definition to CFLAGS in lib.mk. Remove
redundant defines from Makefiles that import lib.mk. Convert any usage of
"#define _GNU_SOURCE 1" to "#define _GNU_SOURCE".
This uses the form "-D_GNU_SOURCE=", which is equivalent to
"#define _GNU_SOURCE".
Otherwise using "-D_GNU_SOURCE" is equivalent to "-D_GNU_SOURCE=1" and
"#define _GNU_SOURCE 1", which is less commonly seen in source code and
would require many changes in selftests to avoid redefinition warnings.
