Moved ckprogs behind LFS_CKPROGS ifdef

Browse Source 
So just like ckreads, ckprogs is now opt-in, requiring both 1. defining
LFS_CKPROGS at compile-time, and 2. passing the LFS_M_CKPROGS flag
during lfsr_mount.

_Unlike_ ckreads, ckprogs is actually a very lightweight feature. So the
difference between compiling with/without ckprogs is really quite small:

                code          stack
  before:      36480           2680
  yes-ckprogs: 36480 (+0.0%)   2680 (+0.0%)
  no-ckprogs:  36428 (-0.1%)   2680 (+0.0%)

It's almost not worth putting behind an ifdef if not for consistency
with ckreads.
