Redirect lxc-attach stdin; restore terminal

Browse Source 
Prevent the lxc-attach pipeline from consuming the host's stdin by redirecting its stdin from /dev/null, keeping /dev/tty available for the recovery menu after SIGINT or failures (avoids "read: read error: Input/output error"). Also restore terminal state after the pipeline by running `stty sane` (errors ignored). Applied these changes to both installation invocation sites in misc/build.func.
