maint: remove dead code

This package has not been compilable with -DCRYPT
since commit v1.4-82-g9d1b943.  Remove final vestiges.
* bits.c (copy_block) [CRYPT]: Remove #ifdef'd code.
* inflate.c (NEXTBYTE) [CRYPT]: Likewise.
Prompted by a report from Flávio Medeiros
that HEADER and T might be used uninitialized.
