This patch is mostly for self-documentation, because _AS_UNSET_PREPARE
is called anyway by AS_SHELL_SANITIZE. However, by default AS_REQUIRE
places stuff in M4SH-INIT and that comes after the find-better-shell test.
This is wrong and this patch fixes it.

* lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Expand
_AS_UNSET_PREPARE in M4SH-SANITIZE.
