unix: add bindings for keyutils syscalls
This CL adds support for the ADD_KEY, REQUESET_KEY, and KEYCTL syscalls.
These syscalls allow access to the kernel keyring facilities. In C code,
these syscalls are wrapped by the libkeyutils package. See:
http://man7.org/linux/man-pages/man7/keyutils.7.html
The ADD_KEY and REQUEST_KEY calls are fairly straightforward, but the
KEYCTL syscall is a multiplexor for a number of key management
functions. See:
http://man7.org/linux/man-pages/man3/keyctl.3.html
The Go bindings for the KEYCTL functions attempt to replicate what
libkeyutils does. This is done via generated helper functions.
