24e5fd3bed fs: remove _POSIX_C_SOURCE defining (fanquake)

Pull request description:

  On Linux systems, `_POSIX_C_SOURCE` will default to `200809L` (since glibc 2.10). There's currently no reason for us to undefine it, and then set it to an earlier value. Also tested with musl libc.

  I think if anything, the project should be settings macros like `_POSIX_C_SOURCE`, globally.
