all: add optional close_fds feature to reproducers
Instead of always closing open fds (number 3 to 30) after each program,
add an options called EnableCloseFds. It can be passed to syz-execprog,
syz-prog2c and syz-stress via the -enable and -disable flags. Set the
default value to true. Also minimize C repros over it, except for when
repeat is enabled.
