config(8): Bump major version after r335998

config-generated hints.c/env.c from r335998 and later are incompatible with
earlier kernels due to no longer setting envmode/hintmode. A minor bump for
this is insufficient, as matching major version with a later minor version
is still viewed as backwards-compatible.

This was an MI kernel change, soo all VERSREQ's are bumped.
