fix #7969
process: throw TypeError if kill pid not a number

Currently, invalid usage such as:

    process.kill('SIGTERM')
    process.kill(null)
    process.kill(undefined);

all coerce the pid to 0, and signal the current process.

Between 0.11.1 and 0.11.2, the message and error events stopped

them usable again. Closes #7998.
