configure: avoid false positive in DragonFlyBSD by default, the max buffer size is 16K and histeresis is at 50%, so a bigger read is needed to unlock writes than you would expect from other BSD (512 bytes) this doesn't introduce any regression on FreeBSD 11.1, OpenBSD 6.1, NetBSD 7.1, macOS 10.12.6 and of course DragonFlyBSD 4.8.1, and most of them show a max pipe size of 64K, so the read call should drain them all regardless of how conservative they are on the free pipe space they will require (usually 512 bytes) before kevent reports the fd as ready for write. I couldn't find a reference to which bug this code was trying to look for and it seems to be there from the beginning of git history so it might be no longer relevant. Issue: #548
