xspawn: Do $PATH resolution up-front
posix_spawnp() is typically implemented like execvp(), i.e., by repeatedly trying execv() with each $PATH component until it succeeds. This is much slower than resolving the executable path up-front and then calling execv() once, so do that. Fixes: https://github.com/tavianator/bfs/pull/127#issuecomment-1795095126
