The caller of mmap expects it to return a positive errno value, but the linux-arm64 and nacl-386 system calls returned a negative errno value. Correct them to negate the errno value. The caller of mincore expects it to return a negative errno value (yes, this is inconsistent), but the linux-mips64x and linux-ppc64x system call returned a positive errno value. Correct them to negate the errno value. Add a test that mmap returns errno with the correct sign. Brad added a test for mincore's errno value in https://golang.org/cl/19457. Fixes #14297.
