std.c: remove unnecessary use of usingnamespace
Thanks to Zig's lazy analysis, it's fine for these symbols to be
declared on platform they won't exist on. This is already done in
several places in this file; e.g. `pthread` functions are declared
unconditionally.

Eliminates one more usage of `usingnamespace` from the standard library.
4 remain.
