golang.org/x/sys/unix currently does not compile on mips nor mipsle as it fails to set the `isBigEndian` variable. This is due to mips and mipsle being missing in the build tag of their respective endian files.

This change adds mips to the build tag of `endian_big.go` and mipsle to the build tag of `endian_little.go` to fix this issue.

This CL introduces the Getrandom syscall. Allowing users of
sufficiently new kernels (3.17) to detect when the operating system
lacks enough entropy to generate cryptographic random data. See:
http://man7.org/linux/man-pages/man2/getrandom.2.html

As we have updated the syscall numbers, the Getrandom function can
just be generated normally. The only other change is to mkerrors.sh
to include the GRND_* flags for getrandom from <linux/random.h>.

It is important to note that currently the mkerrors.sh script cannot
actually be run as it has fallen behind the 4.10 kernel. The GRND_*
flags were added manually.

This was originally part of a larger commit that was split up.
See CL: https://go-review.googlesource.com/37570

The syscall numbers for Linux were out of date, so with the release of
the 4.10 kernel, now seemed like a reasonable time to update them. Note
that this change is mostly additive except that it removes some invalid
syscalls for arm, and it removes all constants that refer to either the
syscall base or total number of syscalls. Previous versions had only
removed some of them.

The updated syscall numbers were pulled directly from a header build
of the 4.10 kernel. This required some minor adjustements to the sysnum
generating perl script and is why the comments at the tops of the
generated files look slightly different. I could include the script I
used to do this, but right now it cannot generate the zerrors and ztypes
files.
