implement fcntl64 hack glibc overrides fcntl with a macro to fcntl64; implement some trickery to bring back fcntl on older toolchain.

rework toolchain registration - support specifying the glibc version. - support picking the default of musl or glibc. - create both zig and go conventions for `--extra_toolchains`.

work-around res_search on older glibcs `res_search` became a proper symbol only in glibc 2.34. Until that it was re-defined in headers, hitting the (in-)famous https://github.com/ziglang/zig/issues/9485 glibc 2.34+: resolv/resolv.h:int res_search (const char *, int, int, unsigned char *, int) Old glibc: resolv/resolv.h:#define res_search __res_search Also, remove the toplevel includes, as they should never be included in the first place: the headers are included explicitly when needed.
