Bug 21113 – std.file.thisExePath on NetBSD depends upon the /proc filesystem

The function `std.file.thisExPath` depends upon the process filesystem being mounted, which isn't the case by default. However, NetBSD provides a sysctl to get the path name similar to FreeBSD, as can be sen in this C snippet: int mib[4] = { CTL_KERN, KERN_PROC_ARGS, -1, KERN_PROC_PATHNAME }; Documentation can be found at: https://netbsd.gw.com/cgi-bin/man-cgi?sysctl+7+NetBSD-current It would be nice to alter the code to make use of this sysctl call instead.

I also noticed that DragonFlyBSD is using procfs too, but has the same sysctl as FreeBSD (though numbered differently of course...): https://man.dragonflybsd.org/?command=sysctl&section=3
