[release-branch.go1.3] include/u.h: define _DEFAULT_SOURCE for new glibc

««« CL 112530043 / c8059ac4e0ec
include/u.h: define _DEFAULT_SOURCE for new glibc

glibc devs have apparently decided _BSD_SOURCE will be
deprecated on Linux, and issue a preprocessor warning if
declaring _BSD_SOURCE without _DEFAULT_SOURCE.

https://sourceware.org/glibc/wiki/Release/2.20

Fixes #8397.
