Mark Johnston 991666adc7 Ensure that libnv can be used when kern.trap_enotcap=1. ... libnv used fcntl(fd, F_GETFL) to test whether fd is a valid file descriptor. Aside from being racy, this check requires CAP_FCNTL rights on fd. Instead, use fcntl(fd, F_GETFD), which does not require any capability rights. Also remove some redundant fd_is_valid() checks to avoid extra system calls; in many cases we were performing this check immediately before dup()ing the descriptor.
