allow clock_gettime and a bit of fmt
alpine on amd64 (under OpenBSD vmd) tries to do a clock_gettime. I don't know why, but it doesn't seem a problem to allow it.
tighten the rules for fcntl
allow only the F_GETFL and F_SETFL commands
drop useless field
was probably added to distinguish between AF_INET and AF_INET6, to use different functions for logging. But it wasn't really used, and now we use getnameinfo anyway.
remove README.md target
leftover from when README.md was generated by gmid.1
