linux: move DCCP_ constants from linux/gnu to linux

closes #3132

these constants come from linux headers, so they should be exposed for
"linux", not just glibc.

this change exposes them for linux/musl and linux/uclibc.

of note, android contains these same constants, but moving it to
linux-like would also expose them on emscripten, which does not have it.
