Subject: [PATCHv8 4/6] binfmt_misc: trivial: replace get_unused_fd() by get_unused_fd_flags(0)

This patch replaces calls to get_unused_fd() with equivalent call to
get_unused_fd_flags(0) to preserve current behavor for existing code.

In a further patch, get_unused_fd() will be removed so that new code
start using get_unused_fd_flags(), with the hope O_CLOEXEC could be
used, either by default or choosen by userspace.
