linux: Add close_range
It was added on Linux 5.9 (278a5fbaed89) with CLOSE_RANGE_CLOEXEC added on 5.11 (582f1fb6b721f). Although FreeBSD has added the same syscall, this only adds the symbol on Linux ports. This syscall is required to provided a fail-safe way to implement the closefrom symbol (BZ #10353). Checked on x86_64-linux-gnu and i686-linux-gnu on kernel 5.11 and 4.15.
