As it is, the `killSignal` is just retrieved from an object and used.
If the signal passed is actually one of the inherited properties of
that object, Node.js will die. For example,
➜ node -e "child_process.spawnSync('ls', {killSignal: 'toString'})"
Assertion failed: (0), function uv_close, file ....core.c, line 166.
[1] 58938 abort node -e "child_process.spawnSync(...)"
1. This patch makes sure that the signal is actually a own property of
the constants object.
2. Extends the killSignal validation to all the other functions.

Export a new common.noop no-operation function for general use.
Allow using common.mustCall() without a fn argument to simplify
test cases.
