github #145: update completion: _install

current to:
  DragonFly 6.4.2, FreeBSD 14.3, NetBSD 10.1, OpenBSD 7.7, macOS 15.6.1

- -S[temp file] removed except for DragonFly; all other BSDs have
  removed this flag, and I can't find a commercial Unix that supports it
- -S[flush] replaces old -S opt on Darwin, FreeBSD
- -S disabled on OpenBSD which still supports it as a noop/compat option
- corrected +N flag to -N
- remove -C for NetBSD, it appears that this was never supported
- several other updates (mostly Net/Free flags added to Darwin/DragonFly)
