Scripts: Add shellcheck directives to silence warnings

Browse Source 
Set also shell because the xz*.in files start with '#!@POSIX_SHELL@'.

SC1003 and SC2016 are only info messages, not warnings. Several other
shellcheck info messages remain. They are safe to ignore, but I didn't
want to disable them now.
