sysutils/polkit: Update to 121

[duchateau.olivier_gmail.com]

Summary

• Update to 121
• Remove Created to: header
• Add SPIDERMONKEY (set by default) and DUKTAPE options
• Remove unneeded patch

Note: Most Linux distribution and OpenBSD switched to Duktape, in the port we still depend of SpiderMonkey (I don't know which one is better).

I would suggest to make Duktape the default, as it is also intended as such by upstream.

I was dogfooding duktape in D34188, but even to this day trying to run say pkexec results in a crash. Perhaps things have improved with this new release (finally) but duktape support needs more testing on our platform before it can be considered the default.

Update diff:

• Switch by default to Duktape, tested with desktop environment (Pantheon) which has polkit agent and with Xfce (there is no polkit agent) → no crash
• Remove redundant _GNU_SOURCE (I wonder if it is important, because it is not available on FreeBSD)
• Add support of procctl(2) in pkexec program

Below options enable for sysutils/polkit

make showconfig

     DUKTAPE=on: Duktape JavaScript backend
     SPIDERMONKEY=off: SpiderMonkey JavaScript backend

Should this be closed? The port is of version 122 already.
