Define _DEFAULT_SOURCE for getentropy in musl

glibc and musl do not make getentropy available from <unistd.h> unless
_BSD_SOURCE (or _GNU_SOURCE) is defined. _BSD_SOURCE, in glibc, triggers
a deprecation warning to use _DEFAULT_SOURCE instead.

It seems _DEFAULT_SOURCE might be fairly broadly defined, but some
Emscripten-based toolchain (which uses musl) didn't end up defining
it for some reason. Just do it explicitly in the source file so it
always works.
