In many places (not all of them though) we can use `unix.`
instead of `syscall.` as these are indentical.
In particular, x/sys/unix defines:
```go
type Signal = syscall.Signal
type Errno = syscall.Errno
type SysProcAttr = syscall.SysProcAttr
const ENODEV = syscall.Errno(0x13)
```
and unix.Exec() calls syscall.Exec().

Since [1], x/sys/unix has a function to convert signal name
to a number. Let's use it and drop home-grown signal map.
While at it, add a test case.

... that prevent sending signals not mentioned in signal map.
Currently these are SIGRTMIN..SIGRTMAX.

Some architectures don't have all the signals listed.
(Those architectures are mips and mips64, which don't have SIGSTKFLT
and SIGUNUSED. The next commit defines the map for mips and mips64.)

commit b517076907 added a check that kill accepts two arguments.
Since the second argument is optional, change it back to accept the
shorter form "kill CONTAINER".

This allows a user to send a signal to all the processes in the
container within a single atomic action to avoid new processes being
forked off before the signal can be sent.
This is basically taking functionality that we already use being
`delete` and exposing it ok the `kill` command by adding a flag.

There are 3 types of EXAMPLE title in manual and code:
1: "# EXAMPLE"
runc-delete.8.md
runc-exec.8.md
runc-kill.8.md
2: "EXAMPE:"
runc-spec.8.md
3: EXAMPLE title exist in manual, but not exist in code's --help output
delete.go
exec.go
kill.go
This patch unified above format, and deleted some useless blanks.

Closes#532
This requires the container id to always be passed to all runc commands
as arg one on the cli. This was the result of the last OCI meeting and
how operations work with the spec.
