This reverts commit 175e6cb75ce328d51a9d4ad18c7e09d9fb92c2e1.

This change is already in bzip2 1.0.7. The change fixing a regression
caused by this change is in 1.0.8 which is the current version in zeus.

This isn't resulting in failures because the patch file isn't included
in SRC_URI.

-Subject: [PATCH] Make sure nSelectors is not out of range
-
-nSelectors is used in a loop from 0 to nSelectors to access selectorMtf
-which is
-UChar    selectorMtf[BZ_MAX_SELECTORS];
-so if nSelectors is bigger than BZ_MAX_SELECTORS it'll do an invalid memory
-access
-Fixes out of bounds access discovered while fuzzying karchive
