package/autofs: fix fsck program paths

Following Arnout review of "autofs: fix mount, umount and fsck program
paths" in https://patchwork.ozlabs.org/patch/1148086, set
ac_cv_path_E2FSCK to /sbin/fsck and ac_cv_path_E{3,4}FSCK to no so that
the fsck wrapper will always gets used (if the e3 and e4 versions don't
exist, the e2 version is used regardless of fs type).
